- Q1. What is closures, Hoisting with example Semantic elements
- Ans.
Closures and hoisting are important concepts in JavaScript.
Closures refer to the ability of a function to access variables in its outer scope even after the function has returned.
Hoisting is the behavior of moving variable and function declarations to the top of their respective scopes.
Example of closures: function outer() { let x = 10; function inner() { console.log(x); } return inner; } const innerFunc = outer(); inn...

React 16 introduced new features like React Fiber, Error Boundaries, Portals, and improved server-side rendering.

Error Boundaries allow developers to catch and handle errors in components.
Portals provide a way to render children into a different DOM subtree.

- Q2. Why react hooks are use full?
- Ans.
React hooks simplify state management and lifecycle methods in functional components.
Hooks allow functional components to have state and lifecycle methods
They reduce the need for class components and HOCs
Hooks make code more readable and easier to test
Examples of hooks include useState, useEffect, and useContext
- Q3. What is HOC components?
- Ans.
HOC components are higher-order components in React that allow code reuse and logic sharing.
HOC components are functions that take a component and return a new component with additional functionality.
They are used to abstract common logic and behaviors into reusable components.
HOC components can be used for tasks like authentication, logging, and code reuse.
Example: a withAuth HOC component that adds authentication log

- Q1. What is hoisting ?
- Ans.
Hoisting is a JavaScript mechanism where variables and function declarations are moved to the top of their scope.
Variables declared with var are hoisted to the top of their scope
Function declarations are hoisted before variables
Function expressions are not hoisted
Hoisting can lead to unexpected behavior and bugs
- Q2. What is useEffect ?
- Ans.
useEffect is a hook in React that allows you to perform side effects in functional components.
It replaces componentDidMount, componentDidUpdate, and componentWillUnmount.
It takes two arguments: a function that performs the side effect and an array of dependencies.
The function is called after every render, unless the dependencies haven't changed.
Common use cases include fetching data, setting up event listeners, and upd...
- Q3. What is function currying
- Ans.
Function currying is a technique of transforming a function that takes multiple arguments into a sequence of functions that each take a single argument.
Currying allows partial application of a function.
It helps in creating reusable functions.
Curried functions are composable and can be easily combined to create new functions.
Currying can be achieved using closures or by using libraries like Lodash or Ramda.
Example: cons
- Q4. What is closures in js
- Ans.
Closures are functions that have access to variables in their outer scope, even after the outer function has returned.
Closures are created when a function is defined inside another function.
The inner function has access to the outer function's variables and parameters.
Closures can be used to create private variables and methods.
Closures can also be used to create functions with pre-set arguments.

- Q1. What do you mean by redux and how to use redux
- Ans.
Redux is a predictable state container for JavaScript apps. It helps manage the state of an application in a more organized way.
Redux is a state management tool commonly used with React to manage the state of an application.
It follows a unidirectional data flow, where the state is stored in a single store.
Actions are dispatched to update the state, and reducers specify how the state should change in response to actions...
- Q2. What is the use of Context Api in React
- Ans.
Context API is used in React to pass data through the component tree without having to pass props down manually at every level.
Avoids prop drilling by providing a way to share values like themes, user data, etc. across the component tree.
Helps in managing global state in React applications.
Context API consists of Provider and Consumer components to provide and consume the context data.
Can be used for theming, localizat
