Immediately invoked function expressions (IIFE) are functions that are executed immediately after they are created.
IIFE is defined and invoked at the same time using parentheses at the end of the function declaration.
Anonymous functions do not have a name and can be used as IIFE by wrapping them in parentheses.
IIFE is commonly used to create a private scope for variables and functions.
Closures are functions that have access to variables from their outer scope even after the outer function has finished executing.
Closures allow functions to access variables from their parent function even after the parent function has returned
They help in creating private variables and functions in JavaScript
Closures are commonly used in event handlers and callbacks
A promise is an object representing the eventual completion or failure of an asynchronous operation.
Promises are used to handle asynchronous operations in JavaScript.
They can be in one of three states: pending, fulfilled, or rejected.
Promises can be chained using .then() method to handle success and failure callbacks.
Example: Fetch API returns a promise when making an HTTP request.
Lazy loading is a technique used in web development to defer loading non-essential resources until they are needed.
Lazy loading helps improve page load times by only loading resources when they are required.
It is commonly used for images, videos, and other media files on a webpage.
Lazy loading can be implemented using JavaScript libraries like Intersection Observer or by using native browser features like loading='lazy

SSR in React is implemented using server-side rendering to pre-render React components on the server before sending them to the client.
Use libraries like Next.js or Gatsby to implement SSR in React.
Configure server to render React components on the server side.
Optimize server-side rendering for performance by caching rendered components.
To change a React project from development mode to production mode, you need to build the project using the 'npm run build' command.
Run 'npm run build' command in the terminal to create a production build of the project.
This command will generate a 'build' folder with optimized and minified files for production.
You can then deploy the contents of the 'build' folder to a web server for production use.
Lazy loading is a technique used to defer loading non-essential resources until they are needed.
Lazy loading helps improve performance by only loading resources when they are required.
In React, lazy loading can be implemented using React.lazy() and Suspense components.
Example: const MyComponent = React.lazy(() => import('./MyComponent'));
Example:
React routing is a way to handle navigation in a React application by defining routes and rendering components based on the URL.
React routing allows for declarative routing, where routes are defined using JSX elements.
It enables dynamic routing based on the URL, allowing for different components to be rendered based on the route.
React Router is a popular library for handling routing in React applications.

A closure is a function that has access to its own scope, as well as the scope in which it was defined.
A closure allows a function to access variables from its outer function even after the outer function has finished executing.
Closures are created whenever a function is defined within another function.
Example: function outerFunction() { let outerVar = 'I am outer'; return function innerFunction() { console.log(outerVa
Async/await is a feature in JavaScript that allows for asynchronous code to be written in a synchronous manner.
Async/await is built on top of promises and provides a more readable and concise way to work with asynchronous code.
The 'async' keyword is used to define a function as asynchronous, allowing it to use the 'await' keyword inside it.
When 'await' is used, it pauses the execution of the function until the promise ...
Use Set to remove duplicates from array of strings.
Create a Set from the array to automatically remove duplicates
Convert the Set back to an array if needed
Example: const arr = ['apple', 'banana', 'apple', 'orange']; const uniqueArr = [...new Set(arr)];
React DOM updates by comparing the virtual DOM with the actual DOM and only updating the necessary components.
React creates a virtual DOM to represent the UI components.
When a state or prop changes, React re-renders the virtual DOM.
React then compares the virtual DOM with the actual DOM to identify the differences.
Only the necessary components are updated in the actual DOM, minimizing performance impact.
React Hooks are functions that let you use state and other React features without writing a class.
React Hooks were introduced in React 16.8.
They allow you to use state and other React features in functional components.
Some commonly used hooks are useState, useEffect, useContext, and useRef.
Hooks make it easier to reuse logic across components.
Hooks can be used to manage component state, perform side effects, and more.
Call, bind, and apply are methods used to manipulate the value of 'this' in JavaScript functions.
Call - invokes a function with a specified 'this' value and arguments provided individually.
Bind - creates a new function that, when called, has its 'this' keyword set to the provided value.
Apply - invokes a function with a specified 'this' value and arguments provided as an array.
Redux Toolkit is a set of tools and best practices to simplify Redux development, while Redux is a predictable state container for JavaScript apps.
Redux Toolkit provides a set of tools like createSlice, createAsyncThunk, and configureStore to simplify Redux setup and reduce boilerplate code.
Redux Toolkit includes immer library for writing immutable update logic in a more convenient way.
Redux Toolkit also includes a def...

Inline and block level elements in HTML/CSS
Inline elements flow in the document in a line, without starting a new line. Examples include , , .
Block level elements start on a new line and take up the full width available. Examples include
,
Microtasks in JavaScript are tasks that are executed asynchronously and have higher priority than regular tasks.
Microtasks are scheduled to run after the current script has finished but before the browser has a chance to render.
They are often used with promises, as promise callbacks are executed as microtasks.
Microtasks are executed in the same event loop iteration as regular tasks, but before the next rendering.

Custom hooks are reusable functions that allow you to extract component logic into separate functions.
Custom hooks are prefixed with 'use' and can call other hooks if needed.
They can be used to share logic between components without duplicating code.
Custom hooks can be created for any kind of logic, such as fetching data, managing state, or handling side effects.
Redux is a predictable state container for JavaScript apps. It helps manage the state of an application in a centralized store.
Create a Redux store to hold the state of the application
Define actions to describe state changes
Write reducers to specify how the state changes in response to actions
Dispatch actions to update the state in the store
Connect components to the Redux store using the connect function from react-red
Redux is a predictable state container for JavaScript apps.
Actions are dispatched to the store
Reducers specify how the state changes in response to actions
Store holds the state of the application
Components can subscribe to the store to access state
Prop drilling is the process of passing props down multiple levels of nested components in React.
Prop drilling occurs when a prop needs to be passed through multiple levels of components that do not need the prop themselves.
It can lead to unnecessary passing of props through intermediate components, making the code harder to maintain.
To avoid prop drilling, you can use Context API, Redux, or React's useContext and useR...
Hoisting is a JavaScript mechanism where variable and function declarations are moved to the top of their containing scope during the compilation phase.
Variable declarations are hoisted to the top of their scope, but not their assignments.
Function declarations are fully hoisted, meaning they can be called before they are declared.
Hoisting can lead to unexpected behavior if not understood properly.
useContext hook allows components to access data from a context without passing props down manually
useContext hook is used to consume a context created by React.createContext
It takes the context object as an argument and returns the current context value for that context
It allows components to subscribe to context changes and re-render when the context value changes
