JavaScript 15 🧬 Arrow functions

a - arrow functions introduction Arrow functions in JavaScript provide a concise syntax for writing functions They are part of the ECMAScript 2015 (ES6) specification. They offer several advantages such as more compact syntax, lexical this binding, and no need for the function keyword. They don't have their own bindings to this, arguments, or super, and should not be used as methods. They cannot be used as constructors and cannot use yield. They cannot be created as generator functions syntax: const functionName = (parameters) = // function body ; The parantheses around parameters can only be omitted if there is a single parameter const squareRoot = a = return a*a ; Curly braces can only be omitted if the function returns an expression const squareRoot = a = return a*a b - Arrow function examples Example 1 → concise syntax, omit parentheses Example 2 → concise syntax, omit curly braces Example 3 → Basic syntax Example 4 → with multiple statements Example 5 → `this` correctly refers to the person object Example 6 → arrow function in array method Example 7 → Arrow functions cannot be used as constructors. TypeError: Foo is not a constructor

Node js V12 – What are the new features in Node js V12

Node.js has been committed about their yearly updates the new features. This year their new version — V12 named Erbium is out. Here is an honest, unbiased review. Before jumping straight into the new features of Node js V12, what Node.js is let me paint what it is and what it does. Node.js is an open source framework that runs on Chrome’s V8 JavaScript engine.  It supports every OS on the market — MAC, Linux and Windows and easy on your budget.

What is Node.js?

Node.js is a platform, that supports building secure, fast and scalable network applications. Node.js is an event-driven model that doesn’t drag and is efficient for data-intensive real-time application that runs across distributed devices. Now, lets see briefly about the features in Node js V12

TLS 1.3 is now used by default Max protocol

TLS stands for Transport Layer Security, that secures communication between servers and browsers. Another notable thing about this feature is that this is the default Max protocol that offers to switch off in the CLI/NODE_OPTIONS. It is comparatively faster than TLS1.2.

Async Stack traces

Another noteworthy feature is to trace the errors of Async Stack. Previously, we won’t trace the errors in the Async await functions. Now, developers can easily do so using the asynchronous call frames of the error.stack property

Let me show you an example,

async function wait_1(x) { await wait_2(x) } async function wait_2(x) { await wait_3(x); } async function wait_3(x) { await x; throw new Error(“Oh boi”) } wait_1(1).catch(e => console.log(e.stack));

This output terminal instantly shows additional details. In this version, we can easily debug the async/wait functions.

Parser

The Node.js v12 switches default http parser to ||http that improves the llhttp-based implementation drastically.

Purpose of heap dumps

Another notable update in the Node.js V12 is the integrated heap dump capability an out of the box experience to examine the memory issues.

Heap size configuration

In V8, the max heap size was limited to 700MB and 1400MB on 32-bit and 64-bit platforms, respectively. The updated version of Node.js V12 supports automation, that ensures the heap size helps to process the large data sets.

Startup time establishment

According to the new release of Node.js V12, improves startup speed approximately 30 % for the main thread. It developed the build time for code cache in built-in libraries and embedded it as a binary. Also it improves the performance in JavaScript parsing

N-API performance in Node.js V 12

Node.js V12 supports enhanced N-API in combination with worker threads. The concept of N-API brings stable and enabled native node modules that can prevent ABI-compatibility come across various Node.js versions.

Runtime engine upgrade to 7.4

The Node.js V12 runs on V8 JavaScript engine which is upgraded to 7.4 and eventually will upgrade to 7.6. It brings the stability with the help of Application Binary Interface (ABI). Additionally, it provides high speed execution, supports ECMAScript syntax, secured memory management and so on.

Compiler

For code base, the minimum requirement of the compiler is GNU Compiler Collection (GCC) 6 and glibc 2.17 on platforms other than MAC OS and Windows. The Node.js is now fully facilitated with optimized compiler and high-level security. Nodejs.org released binaries that use a new tool-chain minimum and it provides efficient compile-time and upgraded security.

Diagnostic report

Last but not least, Node.js includes the additional feature is diagnostic report. It generates the report On-Demand that will be hit by any particular event. The user can ability to identify the abnormal termination in production such as performance, crashes, memory leaks, CPU usage, irrelevant output etc.

This article covers the noteworthy features of the Nodejs Erbium recent version.

Getting Started with Salesforce LWC (Lightning Web Component)

If you are a developer looking to implement Salesforce LWC (Lightning Web Component) with Live Project, you first need to understand the core concepts behind LWC.

Prerequisites

Basic Knowledge of JavaScript: Since Salesforce LWC is built using JavaScript, having a good grasp of ES6 (ECMAScript 6) and modern JavaScript concepts is essential.

Salesforce Environment: You need access to a Salesforce Developer Org to start building LWC applications.

Salesforce CLI: The Salesforce Command Line Interface (CLI) is used to create and deploy Lightning Web Components.

Visual Studio Code: VS Code with Salesforce Extensions is the preferred IDE for LWC development.

Setting Up Salesforce LWC

Follow these steps to set up your environment for Salesforce LWC:

Install Salesforce CLI: Download and install the Salesforce CLI from the official Salesforce website.

Set Up a Salesforce Developer Org: Sign up for a free Salesforce Developer Org where you can practice building Lightning Web Components.

Install VS Code: Install Visual Studio Code and the Salesforce Extension Pack.

Create an LWC Project: Use Salesforce CLI to create a new LWC project by running the following command:

bash

Copy code

sfdx force:project:create --projectname lwc-project

Once your environment is set up, you are ready to start building Salesforce LWC (Lightning Web Component) with Live Project.

Building a Simple Lightning Web Component

Let’s build a basic Lightning Web Component to display a list of Salesforce accounts. This example will help you understand how to work with LWC components, Apex controllers, and Salesforce data.

Step 1: Create an LWC Component

Create a folder in your lwc directory and add the necessary files: HTML, JavaScript, and CSS. The basic structure looks like this:

bash

Copy code

lwc

├── accountList

│   ├── accountList.html

│   ├── accountList.js

│   └── accountList.css

In accountList.html, you’ll define the template for your component:

html

Copy code

<template>

    <lightning-card title="Account List" icon-name="standard:account">

        <ul>

            <template for:each={accounts} for:item="account">

                <li key={account.Id}>

                    {account.Name}

                </li>

            </template>

        </ul>

    </lightning-card>

</template>

In accountList.js, you’ll fetch the account data from Salesforce:

javascript

Copy code

import { LightningElement, wire } from 'lwc';

import getAccounts from '@salesforce/apex/AccountController.getAccounts';

export default class AccountList extends LightningElement {

    @wire(getAccounts)

    accounts;

}

In AccountController.cls, you’ll create an Apex class to fetch data from Salesforce:

apex

Copy code

public with sharing class AccountController {

    @AuraEnabled(cacheable=true)

    public static List<Account> getAccounts() {

        return [SELECT Id, Name FROM Account LIMIT 10];

    }

}

Once this is done, deploy the component to your Salesforce org using the Salesforce CLI.

Step 2: Testing the Component in Salesforce

After deploying, go to App Builder in Salesforce and drag your new LWC component onto a Lightning Page. This simple example illustrates how easy it is to fetch and display Salesforce data using Salesforce LWC.

Live Project with Salesforce LWC (Lightning Web Component)

Now that we’ve covered the basics of Salesforce LWC, let’s move on to implementing a Live Project. The live project will involve building a Salesforce LWC application that allows users to search and display information about Contacts in Salesforce. This project will be more advanced, involving data binding, input fields, and interaction with the Salesforce backend using Apex.

Project Requirements

Search Component: A component that allows users to enter a search term to find Contacts.

List Component: A component that displays a list of Contacts matching the search term.

Detail Component: A component that shows detailed information about a selected Contact.

Step 1: Create the Search Component

The search component will allow users to input a name, which will be passed to an Apex controller to query Salesforce. Create a component called contactSearch:

contactSearch.html:

html

Copy code

<template>

    <lightning-input label="Search Contacts" onchange={handleSearch}></lightning-input>

</template>

contactSearch.js:

javascript

Copy code

import { LightningElement } from 'lwc';

export default class ContactSearch extends LightningElement {

    handleSearch(event) {

        const searchEvent = new CustomEvent('search', {

            detail: event.target.value

        });

        this.dispatchEvent(searchEvent);

    }

}

Step 2: Create the List Component

The list component will display the results of the search. It will receive the search term from the parent component and call the Apex controller to retrieve the data.

contactList.js:

javascript

Copy code

import { LightningElement, api, wire } from 'lwc';

import getContacts from '@salesforce/apex/ContactController.getContacts';

export default class ContactList extends LightningElement {

    @api searchTerm;

    @wire(getContacts, { searchTerm: '$searchTerm' }) contacts;

}

Conclusion

By now, you should have a solid understanding of Salesforce LWC (Lightning Web Component) and how to implement a Live Project. This guide covered both the fundamental aspects of LWC and a hands-on live project, allowing you to experience the real-world application of this powerful framework.

Implementing Salesforce LWC in live projects is crucial for enhancing user interfaces and improving performance within Salesforce applications. Whether you are an experienced developer or a beginner, learning Salesforce LWC can open up new opportunities in the growing Salesforce ecosystem.

a - escape characters escape characters are used to represent special characters in strings example = "This is a backslash: \\"; → This is a backslash: \ example = 'He said, \'Hello!\''; → He said, 'Hello!' example = "She said, \"Hi there!\""; → She said, "Hi there!" example = "Line 1\nLine 2"; → Line 1 Line 2 example = "This is an octal escape: \101 (\u0041 in hex)"; → This is an octal escape: A (Unicode 0x0041) example = "This is a hex escape: \x41 (\u0041 in octal)"; → This is a hex escape: A (Unicode 0x0041) example = "This is a Unicode escape: \u03A9 (Omega symbol)"; → This is a Unicode escape: Ω (Greek Capital Letter Omega) b - template literals template literals provide a new way to work with strings They allow to embed expressions inside string literals using ` This makes it easier to create multi-line strings and perform string interpolation. Template Literals, introduced in ES6 (ECMAScript 2015) let greeting = `Hello, $name!`; → Basic Usage let message = ` This is a multi-line string.` → Multi-Line Strings `The sum of $a and $b is $a + b.` → Expression Interpolation
