  • Q1. Difference between Let, Const and Var. Write code and explain.
  • Ans. 

    Let, Const, and Var are used to declare variables in JavaScript with different scoping and reassignment abilities.

    • Var has function scope and can be redeclared and reassigned.

    • Let has block scope and can be reassigned but not redeclared.

    • Const has block scope and cannot be reassigned or redeclared.

  • Answered by AI
  • Q2. What are state and props. Difference.
  • Ans. 

    State and props are two important concepts in React. State represents the internal data of a component, while props are used to pass data from a parent component to a child component.

    • State is mutable and can be changed within a component.

    • Props are read-only and cannot be modified within a component.

    • State is used to manage component-specific data, while props are used for inter-component communication.

    • State is initializ...

  • Q3. Difference between Promise and Async-Await?
  • Ans. 

    Promise is a callback function that returns a value in the future. Async-Await is a syntax that simplifies working with Promises.

    • Promises are used to handle asynchronous operations and avoid callback hell.

    • Async-Await is a syntax that allows writing asynchronous code that looks like synchronous code.

    • Async-Await is built on top of Promises and uses the same underlying mechanism.

    • Async-Await can only be used within an asyn...

  • Answered by AI
  • Q4. What are 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.

  • Answered by AI
  • Q5. What is Hoisting in JS?
  • Ans. 

    Hoisting is a JavaScript behavior where variable and function declarations are moved to the top of their scope.

    • Hoisting applies to both variable and function declarations.

    • Variable declarations are hoisted but not their initializations.

    • Function declarations are fully hoisted, including their definitions.

    • Hoisting can lead to unexpected behavior if not understood properly.

  • Answered by AI
  • Q6. How does Event Loop works? What are Event Queue and Event Stack?
  • Ans. 

    Event Loop is a mechanism that allows JavaScript to handle asynchronous operations.

    • Event Loop is a continuous process that checks the Event Queue and moves events to the Event Stack.

    • Event Queue holds all the events that are waiting to be processed.

    • Event Stack holds the events that are currently being processed.

    • When the Event Stack is empty, the Event Loop checks the Event Queue for new events.

    • JavaScript uses Event Loop...

    • Redux follows a unidirectional data flow pattern.

    • The application state is stored in a single JavaScript object called the store.

    • Actions are dispatched to describe state changes.

    • Reducers are pure functions that specify how the state should change based on the dispatched actions.

    • Selectors are used to extract ...

  • Answered by AI
  • Q10. How can you optimize a React App?
  • Ans. 

    Optimizing a React app involves reducing bundle size, using lazy loading, and optimizing rendering performance.
