Deep Dive into React States From Imperative to Declarative Programming

The evolution from imperative programming with vanilla JavaScript to modern JavaScript frameworks has revolutionized UI development. Imperative programming required detailed instructions to manipulate the UI, making it inefficient and difficult to scale as projects grew in complexity. Managing highly complex frontend projects was nearly impossible.

Modern JavaScript frameworks such as KnockoutJs, AngularJS, VueJs, and ReactJs were developed to shift from imperative to declarative programming. These frameworks allow programmers to specify what should be displayed, leaving the complex task of rendering to the framework. This shift enabled developers to focus on business logic, making it feasible to build and manage highly complex frontend applications. 

React: A Modern JavaScript Framework

React is a popular and versatile JavaScript framework. It is unopinionated, meaning it provides tools and methodologies but leaves the implementation details to the developer. 

Components in React

Components are the building blocks of a React application. A React app is divided into smaller, manageable, and maintainable pieces of code. Components have two key aspects: props and state. 

Props: Passes from a parent to a child component, props are read-only.

State: Internal to the component and immutable, state can be changed using the setter function. Any change in state causes the component to re-render.

Principles of Structuring State

1. Group Related State: Combine related states. For example, instead of having separate states for longitude and latitude, combine them into a single state representing coordinates.  

2. Prevent State Contradictions: If two states are interdependent and some combinations are impossible, derive one state from the other to avoid contradictions.

3. Eliminate Redundant State: If information can be calculated from props or component state, avoid adding it to the component state.

4. Avoid State Duplication: Duplication of data across multiple variables can cause synchronization issues. Maintain a single source of truth.

5. Minimize Nested State: Deep hierarchies are challenging to update. Prefer a flat state hierarchy whenever possible. 

Sharing State Between Components

When state needs to be shared between components, lift the state to the closest common parent and pass it down via props. This technique is known as state lifting in React. 

Extracting State Logic to Reducers

Managing numerous states and updating them through various event handlers can become complex. Extracting state update logic into a reducer, facilitated by the `useReducer` hook, helps manage this complexity. 

Prop Drilling

As components grow in complexity, passing props through multiple levels becomes cumbersome. This practice is known as prop drilling. To address this, use React’s context. Context allows you to inject data at a higher level and access it in any child component without passing props through each level. 

Combining Reducer and Context API

For effective management of a complex screen, combine the use of reducers and context. A reducer consolidates state update logic, while context allows you to pass data to deeply nested components without props. Inject the data via context at the root level, exposing both the data and the dispatch function to update the state.

i loved seeing the moment of stone realising he was going to stick with robotnik (─‿‿─) could we see the moment ROBOTNIK realises stone is here for good?

Robotnik isn't used to people being happy to see him

DO NOT LET TRUMP DECLARE WAR ON IRAN.

Now that he sees the accelerating success of the Indivisible protests, he will play his ace: becoming a wartime president. This would make it far easier to grant himself emergency powers and shut down dissent in a way that will make the past week look mild.

Donald Trump becoming a wartime president is unacceptable.

you're just NOW telling me python has a built-in method named maketrans() ???? I can make a string trans?

[roseverdict]

programming languages are weird because i struggle with gdscript (a proprietary scripting language for godot meant to be simple to use and understand) but just need to be pointed the right direction for smilebasic (a proprietary version of basic for specifically nintendo systems) and then i'm off to the races without much fuss

like. whose idea was this

[eggofchaos]

big news big news big news

i got into all the grad schools i applied to!!!! woo hoo!

now it's time for the painful part—deliberation time.

From the newsletter:

Imperative Programming Imperative programming describes a sequence of steps that change the program’s state. Languages like C, C++, Java, Python (to an extent), and many others support imperative programming styles.

Declarative Programming Declarative programming emphasizes expressing logic and functionalities without describing the control flow explicitly. Functional programming is a popular form of declarative programming.

Object-Oriented Programming (OOP) Object-oriented programming (OOP) revolves around the concept of objects, which encapsulate data (attributes) and behavior (methods or functions). Common object-oriented programming languages include Java, C++, Python, Ruby, and C#.

Aspect-Oriented Programming (AOP) Aspect-oriented programming (AOP) aims to modularize concerns that cut across multiple parts of a software system. AspectJ is one of the most well-known AOP frameworks that extends Java with AOP capabilities.

Functional Programming Functional Programming (FP) treats computation as the evaluation of mathematical functions and emphasizes the use of immutable data and declarative expressions. Languages like Haskell, Lisp, Erlang, and some features in languages like JavaScript, Python, and Scala support functional programming paradigms.

Reactive Programming Reactive Programming deals with asynchronous data streams and the propagation of changes. Event-driven applications, and streaming data processing applications benefit from reactive programming.

Generic Programming Generic Programming aims at creating reusable, flexible, and type-independent code by allowing algorithms and data structures to be written without specifying the types they will operate on. Generic programming is extensively used in libraries and frameworks to create data structures like lists, stacks, queues, and algorithms like sorting, searching.

Concurrent Programming Concurrent Programming deals with the execution of multiple tasks or processes simultaneously, improving performance and resource utilization. Concurrent programming is utilized in various applications, including multi-threaded servers, parallel processing, concurrent web servers, and high-performance computing.

was invited to one of the programs i applied to's annual research day??? it's next week should i go

[grimark]

*downloads designations congruent with things back onto my phone* haha but seriously what if.

[dilsdesigns]

my friend who's fixing my computer caught my flu 😭

[lord-shitbox]

finally becoming more independent & tbh. this is fine actually dunno why I was even worried. I'm learning my way around the big city on my own & took public transport by myself for the first time & bought myself lunch & met with people & filled out paperwork n it was all literally fine. Waow
