[Hacktoberfest]: Add content for React - Hooks in React

[rakshixh]

📝 Issue Description

Add the following content for Hooks in React under REACT

1. Introduction to Hooks: (What are Hooks, Rules of Hooks)
2. Basic Hooks: [useState (Managing State), useEffect (Handling Side Effects)]
3. Additional Hooks: [useContext (Context API for Global State), useRef (Referencing DOM Elements), useReducer (State Logic for Complex State), useMemo (Memoization to Avoid Unnecessary Re-renders), useCallback (Memoizing Functions)
4. Custom Hooks: (Creating Custom Hooks, When and Why to Use Custom Hooks)

File you will be working on: src\content\docs\react\hooks.mdx

🎯 Expected Outcome

The expected outcome is to add a well-documented and informative section under React that covers the following topics:

• Introduction to Hooks: A detailed explanation of what React Hooks are, including the motivation behind their introduction and the rules of hooks (e.g., only calling hooks at the top level and inside functional components).
• Basic Hooks: A clear guide to the most fundamental hooks:
  • useState: Explanation of how to use the useState hook to manage state in functional components, with examples of how to initialize and update state.
  • useEffect: Explanation of how to use the useEffect hook for handling side effects like data fetching or subscriptions, with examples of controlling when effects run and how to clean them up.
• Additional Hooks: A deeper dive into other important hooks in React:
  • useContext: Guide on how to use the useContext hook for accessing values from the Context API to manage global state.
  • useRef: Explanation of the useRef hook for referencing DOM elements and persisting values across renders without triggering re-renders.
  • useReducer: A comprehensive guide on using the useReducer hook to manage complex state logic, particularly in large-scale applications.
  • useMemo: Explanation of the useMemo hook to memoize expensive calculations and avoid unnecessary re-renders, with practical examples.
  • useCallback: Explanation of the useCallback hook to memoize functions and improve performance in React applications, with examples demonstrating the need for memoizing functions.
• Custom Hooks: Instructions on how to create custom hooks to extract reusable logic across components, including when and why to use custom hooks, with real-world examples.

The content should be written clearly, with examples where necessary, and provide value for developers who are new to hooks or looking to deepen their understanding of React Hooks. Please don't make use of the AIs.

🔧 Solution Guidance (Optional)

• Make use of Astro Star Light Components

📋 Steps to Reproduce

• Navigate to src\content\docs\react\hooks.mdx file in the repository.
• Add content for each of the 4 sections mentioned above.
• Ensure the content is formatted properly using MDX

Hi there,

Can I work on this ?

[Nitheesh-2003]

Hi @rakshixh,

Whether I need to add Astro components in all the examples ? Because certain examples are somewhat small. So, if I add Astro Components as well it will make it complex. Can you clear my doubt.

[rakshixh]

Hey @Nitheesh-2003

Yeah because it will maintain the ui across the site. Even if it is small code snippet! All you need to do is import that component from astro in mdx file then dump the code file in txt format inside the 'codes/{your issue folder}/{code snippet file}.txt'

Please note that we have already created folder so that you can dump n number of code snippet txt files inside that folder! Please check the folder structure! If you have any further questions please ask!

[rakshixh]

But in case of hooks if you are displaying only const [file , setFile] = useState();

This you can use md format no need to use the astro component!

But if the snippet is more than 2 lines including brackets etc then please use astro components!

[Nitheesh-2003]

One more clarification, Actual code will be in the code directory. Then whether I need to mention something in place where the example needs to be placed in the mdx file

[rakshixh]

One more clarification,

Actual code will be in the code directory. Then whether I need to mention something in place where the example needs to be placed in the mdx file

Actual code will be inside the Codes/{file-folderName}/

Please nite that codes directory will be under the main dropdown on which you are working for example: if your working on React then path will be React/Codes/{file-folderName}/

You no need to specify the path in mdx!

But to display the code in mdx file you need to import that code file into mdx. You can refer astro's code component to know how to display code!
