Optimizing Performance in MEAN vs MERN Stack Applications

Introduction

In the world of web application development, choosing the right stack can make a significant difference in how your project performs, scales, and adapts to change. Both MEAN Stack development and MERN Stack development are popular choices, each offering its own set of tools and benefits. Whether you’re working with a MEAN Stack development company or a MERN Stack development company, understanding how these technologies behave under the hood will help you deliver faster, more reliable applications to your users.

Understanding the Core Components

At their heart, both MEAN and MERN stacks share the same four-layer architecture: a database, a server environment, an application framework, and a front-end library or framework. MEAN stands for MongoDB, Express.js, Angular, and Node.js, while MERN swaps Angular for React. MongoDB provides a flexible document-based data store, Express.js handles routing and middleware, and Node.js powers the server with its single-threaded, event-driven model. On the front end, Angular brings a full-featured framework with two-way data binding, whereas React offers a lightweight, component-based library that uses a virtual DOM for efficient updates.

Performance Characteristics of MEAN Stack Applications

MEAN Stack applications benefit from Angular’s comprehensive tooling and built-in change detection, which can help manage complex data flows out of the box. Angular’s ahead-of-time (AOT) compilation reduces runtime overhead, translating templates into optimized JavaScript before the browser ever loads them. However, because Angular is feature-rich, the initial bundle size can be larger, affecting the time it takes for users to see the first meaningful paint. With a MEAN Stack development company, you can lean on practices like lazy loading of modules and code splitting to keep the application responsive, loading only what’s necessary when it’s needed.

Performance Characteristics of MERN Stack Applications

MERN Stack development companies often praise React’s minimalistic core and the ability to pick and choose additional libraries to suit a project’s needs. React’s virtual DOM shines in scenarios where frequent UI updates occur, as it batches and diff-checks operations to minimize actual DOM manipulations. The downside? Developers need to assemble their own toolchain—state management, routing, form handling—which can introduce inconsistencies if not managed carefully. Yet, this flexibility allows for highly optimized builds: tree-shaking removes unused code, and server-side rendering (SSR) or static site generation (SSG) can be added to speed up initial page loads and improve SEO.

Shared Performance Optimization Strategies for MEAN and MERN Stacks

Regardless of whether you choose MEAN or MERN, some best practices apply across the board. Compressing assets like JavaScript and CSS using gzip or Brotli reduces payload sizes. Enabling HTTP/2 or newer protocols allows multiple resources to load over a single secure connection. Caching static assets with proper cache-control headers ensures repeat visitors experience lightning-fast page loads. On the database side, indexing frequently queried fields in MongoDB can drastically cut down response times. Finally, profiling server-side code with tools like Node’s built-in profiler highlights bottlenecks in route handlers or middleware, guiding targeted refactoring.

Frontend-Specific Optimization Techniques: Angular vs React

When optimizing an Angular-based front end, leverage change detection strategies such as OnPush to limit re-renders only to components whose inputs have truly changed. Use Angular CLI’s built-in budler to analyze bundle sizes and eliminate redundant code. In contrast, for React, employ memoization with React.memo() or useMemo to avoid unnecessary re-renders of pure functional components. Dynamic imports let you break the UI into smaller chunks, loading heavy components only when users navigate to them. Both ecosystems benefit from performance budgets: setting a size threshold for individual bundles keeps teams aware of the impact of new dependencies.

Optimizing React Performance in MERN Stack Applications

Within a MERN Stack development project, React performance can be taken further by implementing SSR or SSG through frameworks like Next.js. SSR improves time-to-first-byte by rendering HTML on the server, while SSG pre-builds pages at compile time, serving them as static files. When dynamic data is involved, incremental static regeneration combines the best of both worlds. Additionally, integrating a content delivery network (CDN) for your React assets offloads traffic from your Node.js server and brings resources closer to users worldwide. Finally, monitoring bundle sizes with tools like Webpack Bundle Analyzer ensures growth remains in check.

Backend-Level Performance Enhancements for Both Stacks

On the server side, clustering your Node.js process across multiple CPU cores ensures that incoming requests are spread evenly, increasing throughput. Utilizing connection pooling with MongoDB drivers reduces latency by reusing existing database connections. For compute-intensive tasks—image processing, encryption, or complex calculations—delegating work to a message queue (e.g., RabbitMQ or Redis streams) decouples these jobs from the request-response cycle, keeping APIs snappy. Applying rate limiting and request throttling guards against traffic spikes and malicious actors, maintaining stability under load.

Choosing Between MEAN vs MERN Based on Performance Needs

Your choice between MEAN Stack development and MERN Stack development often hinges on project requirements and team expertise. If you need a structured framework with best practices baked in and prefer convention over configuration, Angular within the MEAN stack provides a ready-made environment for large-scale applications. Conversely, if you value modularity, lightweight builds, and the freedom to select your own libraries, React in the MERN stack affords greater flexibility. A MERN Stack development company may be more agile in adopting the latest tools, while a MEAN Stack development company might excel at delivering comprehensive solutions with fewer third‑party dependencies.

Conclusion

Performance is a multi‑layered concern that touches every part of your application—from the database to the server, down to the tiniest UI component. Both MEAN and MERN stacks are capable of delivering robust, high‑speed web applications when approached thoughtfully. By understanding the strengths and trade‑offs of Angular and React, applying shared optimization techniques, and tailoring your choice to your team’s skill set and business goals, you’ll be well on your way to launching fast, responsive apps that delight users. Whether you partner with a MEAN Stack development company or engage a MERN Stack development company, prioritize ongoing performance monitoring and continuous improvement to keep your applications running at peak efficiency.

GitHub Copilot for Azure: New Tools Help AI App Development

GitHub Copilot for Azure

Azure at GitHub Universe: New resources to make developing AI apps easier

Microsoft Azure is to be part of this shift as a development firm that produces for other developers. Many of its employees will be at GitHub Universe to share their experiences and learn from others about how artificial intelligence is changing the way we work. I’m thrilled to share new features and resources incorporating Microsoft Azure AI services into your preferred development tools.

Microsoft’s AI-powered, end-to-end development platform, built on a solid community, seamlessly integrates Visual Studio (VS) Code, GitHub, and Azure to assist you in transforming your apps with AI. For more information, continue reading.

What is GitHub Copilot?

GitHub Copilot is an AI-powered coding assistant that makes it easier and faster for developers to create code. As developers type, it offers contextual aid by suggesting code, which could be a line completion or an entirely new block of code.

Code creation

Full lines and functions can be generated using Copilot. You can write code and have Copilot finish it or describe it in normal language.

Fixing errors

Copilot can remedy code or terminal errors.

Learning

Copilot can help you master a new programming language, framework, or code base.

Documentation

Copilot generates documentation comments.

A large language model (LLM) generates fresh content for Copilot by analyzing and processing massive volumes of data. It writes JavaScript, Python, Ruby, and TypeScript.

Copilot works in your IDE or command line. It’s also available on GitHub.com for enterprise users.

GitHub Copilot for Azure, your expert, is now available in preview

GitHub Copilot for Azure expands on the Copilot Chat features in Visual Studio Code to assist you in managing resources and deploying apps by connecting with programs you currently use, such as GitHub and Visual Studio Code. Without revealing your code, you can receive tailored instructions to learn about services and tools by using “@ azure.” Using Azure Developer CLI (azd) templates to provision and deploy Azure resources helps speed up and simplify development. Additionally, GitHub Copilot for Azure assists you with troubleshooting and answering inquiries regarding expenses and resources, allowing you to devote your time to your preferred activities while GitHub Copilot for Azure handles the rest.

You can easily set up and connect in to your Azure account to grow from free token usage to premium endpoints with enterprise-level security and monitoring in production after you’ve chosen your model and are prepared to configure and deploy.

Use the GitHub Copilot upgrade assistant for Java to streamline Java Runtime updates

It can take a lot of time to keep your Java apps updated. The GitHub Copilot Java upgrade helper provides a method that uses artificial intelligence (AI) to streamline this procedure and enable you to update your Java apps with less manual labor. The GitHub Copilot upgrade assistant for Java, which is integrated into well-known programs like Visual Studio Code, creates an upgrade plan and walks you through the process of upgrading from an older Java runtime to a more recent version with optional dependencies and frameworks like JUnit and Spring Boot.

Using a dynamic build or repair loop, the assistant automatically resolves problems during the upgrade, leaving you to handle any remaining mistakes and apply changes as needed. By granting you complete control and enabling you to take advantage of improved AI automation at every stage, it guarantees transparency by giving you access to logs, code modifications, outputs, and information. After the upgrade is finished, you can quickly go over the comprehensive summary and check all code changes, which makes the process seamless and effective and frees you up to concentrate on creativity rather than tedious maintenance.

Use CI/CD workflows to scale AI apps with Azure AI evaluation and online A/B testing

You must be able to conduct A/B testing at scale and regularly assess your AI applications given trade-offs between cost, risk, and business impact. GitHub Actions, which can be easily included into GitHub’s current CI/CD workflows, are greatly streamlining this procedure. After changes are committed, you can use the Azure AI Evaluation SDK to compute metrics like coherence and fluency and perform automatic evaluation in your CI workflows. After a successful deployment, CD workflows automatically generate and analyze A/B tests using both custom and off-the-shelf AI model metrics. You can also interact with a GitHub Copilot for Azure plugin along the route, which facilitates testing, generates analytics, informs choices, and more.

You can trust Azure with your business, just as we trust it with ours

The platform you select is important as you investigate new AI possibilities for your company. Currently, 95% of Fortune 500 businesses rely on Azure for their operations. Azure is also used by its company to run programs like Dynamics 365, Bing, Copilots, Microsoft 365, and others. You have access to the same resources and tools that it use to create and manage Microsoft. Building with AI on Azure is made easier by its interaction with GitHub and Visual Studio Code.

Quote of the Week

Just to provide another perspective: if you can write the programs you want to write, then all is good. You don't have to use every single tool in the standard library.

I co-authored the Rust book. I have twelve years experience writing Rust code, and just over thirty years of experience writing software. I have written a macro_rules macro exactly one time, and that was 95% taking someone else's macro and modifying it. I have written one proc macro. I have used Box::leak once. I have never used Arc::downgrade. I've used Cow a handful of times.

Don't stress yourself out. You're doing fine.

Introduction to MoonBit, a New Language Toolchain for Wasm - The New Stack

[magazineswire]

JavaScript is one of the most popular programming languages used for web development, known for its flexibility and wide range of applications. However, like any other programming environment, developers occasionally run into errors that can be puzzling and frustrating. One such error is the "TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown File Extension '.javascript' for c:\xxxx\xxxxx\xxxxx-xxxx\xxxxxxxxx.javascript". This article will delve into the causes of this error and provide solutions to resolve it.

Understanding the Error

The error message "TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown File Extension '.javascript'" typically occurs in Node.js environments. Node.js, a runtime built on Chrome's V8 JavaScript engine, allows developers to execute JavaScript code outside of a web browser. However, it expects JavaScript files to have a specific set of extensions, primarily .js.

When Node.js encounters a file with an unfamiliar extension such as .javascript, it throws this type error because it does not know how to handle it. This is a strict file extension checking mechanism to ensure that only known and supported file types are processed.

Common Causes

Incorrect File Extension: The most common cause of this error is using an unconventional file extension like .javascript instead of the standard .js.

Misconfigured Module Loader: Sometimes, custom module loaders or bundlers may be misconfigured to process non-standard file extensions incorrectly.

Typographical Errors: Simple typos or mistakes in the file name or extension can lead to this error.

Toolchain Issues: Certain build tools or task runners may not recognize the .javascript extension, causing them to throw this error.

Solutions

1. Rename the File Extension

The simplest solution is to rename your file extension from .javascript to .js. This ensures compatibility with Node.js and most JavaScript development tools.

Steps to Rename:

Navigate to the directory containing the problematic file.

Rename the file from xxxxxxxxx.javascript to xxxxxxxxx.js.

On Windows, you can do this via File Explorer:

Right-click the file, select "Rename", and change the extension.

On macOS or Linux, you can use the mv command in the terminal:

mv c:\xxxx\xxxxx\xxxxx-xxxx\xxxxxxxxx.javascript c:\xxxx\xxxxx\xxxxx-xxxx\xxxxxxxxx.js

2. Configure Custom Extensions in Node.js

If you have a specific reason to use the .javascript extension, you can configure Node.js to recognize it. This involves creating a custom loader.

Creating a Custom Loader:

Create a file named loader.mjs.

Implement a loader function to handle .javascript files.

Use the --loader option when running your Node.js application.

Example loader.mjs:

import { readFile } from 'fs/promises'; export function resolve(specifier, context, defaultResolve) { if (specifier.endsWith('.javascript')) { specifier = specifier.slice(0, -11) + '.js'; } return defaultResolve(specifier, context); } export async function load(url, context, defaultLoad) { if (url.endsWith('.javascript')) { const source = await readFile(new URL(url), 'utf8'); return { format: 'module', source }; } return defaultLoad(url, context); }

Run Node.js with the custom loader:

node --loader ./loader.mjs c:\xxxx\xxxxx\xxxxx-xxxx\xxxxxxxxx.javascript

3. Adjust Toolchain Configurations

If you are using build tools like Webpack, Babel, or Gulp, you may need to configure them to recognize and process .javascript files correctly.

Example for Webpack: Modify your webpack.config.js:

module.exports = { // Other configurations... resolve: { extensions: ['.js', '.javascript'] }, module: { rules: [ { test: /\.javascript$/, use: 'babel-loader', }, ], }, };

4. Check for Typos

Sometimes, the error might simply be due to a typo. Double-check the file extension and ensure it is correctly typed.

Conclusion

The "TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown File Extension '.javascript'" error can be easily resolved by renaming your file to use the .js extension, configuring a custom loader in Node.js, or adjusting your build tool configurations. Understanding and addressing these issues will help maintain a smooth development workflow and prevent such errors from disrupting your projects.

[rictic]

or how about naming of build tools. we've got a class of program that takes source files, parses them, does a sequence of semantics-preserving (in theory lol) transformations to optimize them, then converts them to a format that's easier for the machine to execute. what would you call that? oh yes, "compiler", aka a tool that takes multiple files and combines them into one file.

like, really? that's the most trivial thing that compilers do! but that's not the worst of it!

a lot of the work of combining files together actually happens in a totally different tool that we call the "linker" (or, in javascript land, the "bundler")

so the dumb thing that compilers are named after, they mostly don't even do! the "compiler" mostly just does an optimized transformation of a smallish bit of code

unless! unless the language that you're transforming into isn't something that's enough like machine code. if it's too high level, we decided that it should have a different, less prestigious name. so we called those compilers transpilers. and those tend to do even less of the "combining multiple files into one" operation, they're usually file by file!

all of this foolishness ultimately serves to make compilation toolchains seem even more intimidating and offputting to noobs, when they're actually some of the coolest and most fun things to hack on

I thought i was missing something massive about 'the' heap as in memory because there must be some deep link to the heap data structure but no turns out they're just called the same thing but are basically unrelated and heap memory is way simpler than i thought.

Top 5 programming dialects for frameworks administrators to learn

Top 5 programming dialects for frameworks administrators to learn 

1. Python By and by fixing most of the programming language records for late years is Python. Is there anything it can't do? This language is known for its adaptability in scaling electronic applications; its capacity to run on most stages, which implies that applications made with Python can be utilized over completely upheld gadget types minus any additional adjustment; and its convenience. These things make it among the simpler programming dialects to realize, which proves to be useful when working with it. It's not without its cons, however, especially when utilized in the portable space or by ethicalness of it being for the most part more slow in light of the fact that it's a deciphered language. Python designers actually discover its qualities to be more noteworthy than its shortcomings in general. 

2. JavaScript The second programing language is JavaScript is tremendous in the versatile workspace, and there's a lot of reasons it should be. A couple of its heavenly professionals: Flexibility, shortsighted usage, a simple section point for learners, enormous help network, superb interoperability with other programming dialects, and it runs exceptionally quick. It is viewed as the prevailing language of the web with about 95% of sites utilizing it somewhat or another. Another credit to JavaScript is that all cutting edge programs have an underlying JavaScript motor which permits it to handle contents customer side a lot quicker than worker side contents. It has its provisos, as everything dialects do, including that JavaScript is frequently misused by danger entertainers to infuse malevolent code on clients' PCs which have prompted many handicapping it on their frameworks. Moreover, JavaScript can here and there be deciphered marginally uniquely in contrast to program to program which can (and will) change the experience for the end client. 

3. PHP PHP is viewed as a backend programming language, which implies it regularly zeros in additional on how it handles interconnections among workers and information dealing with than the general look or GUI (frontend) that clients will in general zero in on. All things considered, PHP has various qualities in this domain, for example, it being a steady, adult language with a plenty of amazing structures to fill in as the establishment to drive pretty much any kind of site or administration. It's upheld by a somewhat enormous environment of network individuals, including instruments and robotized apparatuses for testing and organizations. Geniuses’ aside, among the PHP cons are that improvement in PHP is in some cases more slow contrasted and different dialects on this rundown. It's additionally not as secure by plan as its rivals and is a smidgen more dependent on augmentations for adding backing and highlights. SEE: Git direct for IT experts (free PDF) (TechRepublic)

 4. Go Otherwise called Golang, this language has extraordinary help for multi-stringing and loans itself well to appropriated frameworks as it dominates in scaling. It additionally helps that it was planned by Google Architects and has strong help from the hunt monster, in any event, executing it as the base of its compiler toolchain and WebAssembly. The programming language is among the more up to date ones contrasted and the others on this rundown, however as Han Solo said of the Thousand years Bird of prey, "… she has it where it matters most, kid." Adding to its exemplifications, Go is among the simpler dialects to learn because of its dependence on cleaner grammar, and it's assembled which makes it very quick, and is made innately secure by plan. A few worries with utilizing Go originate from an absence of adaptability, as it's principally pointed toward tending to issues that emerge from working with multicore, arranged, and working with enormous datasets. Additionally, complex applications written in Go can be less proficient on occasion, given its absence of virtual machine.

 5. Java Not exclusively is Java among the more adult programming language dialects, however it is additionally among the most intensely utilized, well, all over, as Java can be found in web applications, yet in addition Blu-Beam players, venture applications, cell phones, etc. One of the primary explanations behind its universality lies in the crucial conviction of, "Compose once, run anyplace." This use the Java establishment no matter how you look at it so it is a similar paying little mind to the gadget or application which contains it so it should, in principle, run a similar without fail. There's an explanation Java is so vigorously depended upon given its strength and stage autonomy, yet that likewise comes at the expense of its memory the executives capacities and more slow than-normal execution, when contrasted with locally agreed applications running on comparative assets. While this rundown was distinctly to zero in on the main 5 dialects, I really wanted to incorporate Ruby— and likewise Ruby on Rails—in view of the structures that make it one of the pioneers in web advancement. Like PHP above, Ruby is frequently viewed as even more a backend programming language and conveys with it a huge network of educated allies, it has an extraordinary number of libraries and devices for building highlight rich sites, and solid, norms based adherence. Despite the fact that it's not as standard as a portion of the contending dialects on this rundown, it is known for its qualities in online business, as confirmed by certain sites that were made utilizing Ruby, as AirBNB and Hulu. It isn't without its issues, for example, burning-through assets unreasonably, which can prompt horrible showing, and it can develop to be very perplexing, which means those new to the language can have an extremely more troublesome time with the expectation to absorb information. Designer Fundamentals Bulletin From the most sizzling programming dialects to the positions with the most significant compensations, get the engineer news and tips you need to know. Week after week Join today likewise observe 03 Scientists discover route for altered programming of human immature microorganisms Initiated pluripotent immature microorganisms (iPS) can possibly change over into a wide assortment of cell types and tissues for drug testing and cell substitution treatments. Be that as it may, the "plans" for this change are frequently muddled and hard to execute. Analysts at the Middle for Regenerative Treatments Dresden (CRTD) at TU Dresden, Harvard College (USA) and the College of Bonn have figured out how to deliberately separate several distinct cells rapidly and effectively from iPS utilizing record factors, including neurons, connective tissue and vein cells. Scientists can utilize this record factor source through the non-benefit association Addgene. The outcomes have now been distributed in the diary Nature Biotechnology. The analysts utilized human incited pluripotent foundational microorganisms (iPS), which were reconstructed from connective tissue cells into a semi undeveloped state. On a fundamental level, iPS cells can be utilized to acquire a wide range of separated cells, from neurons to vein cells, with every formula being exclusively adjusted. "Most separation conventions are exceptionally difficult and confounded. It's unrealistic to acquire distinctive cell types from iPS all the while and in a controlled way in a solitary culture," clarifies Prof. Dr. Volker Busskamp, who works at the Eye Center and the ImmunoSensation2 Bunch of Greatness at the College of Bonn the Greatness Group Material science of Life (PoL) and at the CRTD at TU Dresden. Along with a group from Harvard College, TU Dresden and the College of Bonn, he intended to supplant the confounded methods with basic "plans". Utilizing an enormous scope screening measure, the specialists found a sum of 290 DNA-restricting proteins that rapidly and productively reinvent foundational microorganisms into target cells. The scientists had the option to exhibit that simply a solitary record factor is adequate for each situation to determine separated neurons, connective tissue, vein and glial cells from the immature microorganisms inside four days. The last coat neurons as "covers". A hereditary switchboard for foundational microorganism separation Utilizing robotized techniques, the specialists presented the DNA arrangement for the separate record factor and other control components into the undifferentiated cell genome. The record components could be actuated by adding a little atom, causing a portion of the transgenic foundational microorganisms to be changed over into separated cells. It was then conceivable to recognize and naturally sort undifferentiated organisms and separated cells utilizing cell markers. The specialists along these lines researched the amount of a specific record figure was available the separated cells contrasted with the undifferentiated organisms. The more prominent the distinction, the more significant the particular record factor is by all accounts for the change of iPS into separated cells." Prof. Dr. Volker Busskamp The group utilized this strategy to test an aggregate of 1732 potential record factors on three distinctive undeveloped cell lines. The specialists found an impact for 290 diverse record factors that made the iPS convert into separated cells. This is a new area, since this property of the iPS programming of 241 of the found record factors was already obscure. Utilizing the case of neurons, connective tissue, vein and glial cells, the analysts performed different tests to show that the changed over cells are fundamentally the same as human body cells in their practical capacity. The outcomes open additional opportunities in exploration "The benefit of the distinguished record factors is that they can change over iPS into body cells especially rapidly and effectively and that they can conceivably additionally be utilized to shape more unpredictable tissues," says Busskamp. What took weeks or even months currently occurs inside days. Rather than exorbitant and tedious conventions, a solitary record factor is suffici

And my point is that if JavaScript were straightforwardly usable we wouldn't have ~20 competing packages trying to shore it up.

As for native support for video, audio, and custom elements, that's true of most UI frameworks, I think. GTK, Qt, JavaFX all have some degree of support for all of that. They all also have some kind of XML-derived markup language for describing a document. They all have some kind of pseduo-CSS for styling UI elements. They can all implement some manner of 'responsive UI'.

There are differences between these toolchains, don't get me wrong. Some are better than others. Not gonna catch me using Xaw in 2025. But they've all converged into more-or-less the same sort of shape. MVC is the best pattern we've been able to come up with. XML is the best way to structure documents we've been able to come up with.

But they all suck! They all have sour spots! Nobody is really, truly, totally happy with what they've got! We've been churning this damn pot for fifty years now!

Is there anywhere we can go from this? I dunno. Maybe MVC w/ XML, a scripting language, and some hooey on the backend is the best we'll ever come up with. Maybe the superficial simplicity of UI design principles will just never translate to lines of code without headaches.

I hope we do find something better, though. Or at least finally quash the ridiculous notion that weak, dynamic typing is somehow superior to strong, static typing because it makes the concatenation operator two characters shorter or whatever.

Been learning Qt6 (still to see whether it's a good career move) and while QML is a step in the right direction. There is still some eldritch horror in it.

Something like Repeater in something like React is fairly easy to implement (with some caveat on keys) in Qt it is implemented by 500 lines of (macro- and cast-heavy) C++.

WebAssembly

By now, you might have heard about WebAssembly. However it still seems rather new to a lot of web developers out there. So what is it? It’s really an open standard that includes an assembly language and a binary format for use in applications, such as those that run in a browser. Essentially, It allows for different languages to be run on the web, which can be very useful for enabling high-performance apps on the browser. Ever wanted to run your C++ high-performance graphics application in the browser? Now you can!

Before WebAssembly there was asm.js: a highly optimizable subset of JavaScript designed to allow other languages to be compiled into it while maintaining high performance characteristics that allowed applications to run much faster than regular JavaScript. So web applications now had a way to perform more efficiently on the browser. Compilers to JavaScript existed before asm.js, but they very terribly slow. WebAssembly, however, went one step further and completely took JavaScript out of the picture. This is now done with Wasm (WebAssembly for short) by compiling a language such as C++ into a binary file that runs in the same sandbox as regular JavaScript. A compiler capable of producing WebAssembly binaries, such as Emscripten, allows fo the compiled program to run much faster than the same program written in traditional JavaScript. This compiled program can access browser memory in a fast and secure way by using the “linear memory” model. Basically this means that the program can use the accessible memory pretty much like C++ does.

WebAssembly is useful for facilitating interactions between programs and their host environments, such as on devices which translate higher code into byte-size code. It is also useful in heavier-weight applications. For example, you can now run CAD software on the browser. WebAssembly removes some limitations by allowing for real multithreading and 64-bit support. Load-time improvements of the compiled programs can be achieved with streaming and tiered compilation, while already compiled byte code can be stored with implicit HTTP cacheing. WebAssembly can sometimes even be faster than native code, and is being utilized in things like CLI tools, game logic, and OS kernels.

Still, there are some things that WebAssembly lacks. Calls between WebAssembly and JavaScript are slow, lacking ES module integration and without a means for easy or fast data exchanges. Toolchain integration and backwards compatibility can also be largely improved on. When transpiling from other languages, garbage collection integration is not great; neither is exception support. Debugging is also a pain, as there is no equivalent of DevTools for WebAssembly.

But the advantages of using WebAssembly are still very intriguing: JavaScript that runs on the browser puts all of its code in a “sandbox” for security purposes; however, with WebAssembly, you can have the browser sandbox, while taking the code out of the browser and still keeping the performance improvements! This could better than Node’s Native Modules, although WebAssembly doesn’t have access to system resources without having to pass system functions into it.

WebAssembly is still in its early stages and is not yet feature complete. Features are still being “unlocked” like a skill tree in a video game. But this doesn’t mean it hasn’t already made an impact in the application development space. Will it be on your list of things to try in 2020?
