  • Q1. What are custom hooks in React, and what are their use cases? Additionally, can you provide an example of a custom hook that performs an API call and utilizes the retrieved data?
  • Ans. 

    Custom hooks in React are reusable functions that allow you to extract component logic into separate functions for better code organization and reusability.

    • Custom hooks are created using the 'use' prefix and can be used to share logic between components.

    • Use cases for custom hooks include fetching data from an API, handling form state, managing local storage, and more.

    • Example of a custom hook for API call: const useFetc...

  • Q2. What is the difference between useMemo and useCallback in React?
  • Ans. 

    useMemo is used to memoize a value, while useCallback is used to memoize a function.

    • useMemo is used to memoize a value and recompute it only when its dependencies change.

    • useCallback is used to memoize a callback function and prevent unnecessary re-renders.

    • Example: useMemo can be used to memoize the result of a complex computation, while useCallback can be used to memoize an event handler function.

  • Q3. What is the difference between class-based components and functional components in React?
  • Ans. 

    Class-based components use ES6 classes and have lifecycle methods, while functional components are simpler and use functions.

    • Class-based components use ES6 classes to create components, while functional components are created using functions.

    • Class-based components have lifecycle methods like componentDidMount and componentDidUpdate, while functional components do not.

    • Functional components are simpler and more lightweig...

    • Return a cleanup function inside useEffect to mimic compo

  • Answered by AI
  • Q5. What are the various state management techniques available in React?
  • Ans. 

    Various state management techniques in React include Context API, Redux, and local state.

    • Context API: React's built-in solution for passing data through the component tree without having to pass props down manually at every level.

    • Redux: A popular state management library for React applications, allowing for a centralized store to manage application state.

    • Local state: Managing state within individual components using us

  • Answered by AI
  • Q6. What is the architecture of Redux, and what purposes do middlewares serve within it?
  • Ans. 

    Redux is a predictable state container for JavaScript apps. Middlewares are functions that intercept actions before they reach the reducer.

    • Redux follows a unidirectional data flow architecture.

    • Middlewares in Redux are functions that can intercept, modify, or dispatch actions.

    • Common use cases for middlewares include logging, asynchronous API calls, and handling side effects.

    • Examples of popular Redux middlewares are Redu...

  • Q7. What is hoisting in JavaScript?
  • Ans. 

    Hoisting in JavaScript is the behavior 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 initializations.

    • Function declarations are fully hoisted, meaning they can be called before they are declared.

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

  • Answered by AI
  • Q8. What is event bubbling in JavaScript?
  • Ans. 

    Event bubbling is the propagation of events from the target element up through its ancestors in the DOM tree.

    • Events triggered on a child element will 'bubble up' and trigger on parent elements.

    • Event listeners can be attached to parent elements to handle events from multiple child elements.

    • Stopping event propagation can be done using event.stopPropagation() or event.stopImmediatePropagation().

  • Answered by AI
  • Q9. What are block scope and function scope in JavaScript?
  • Ans. 

    Block scope and function scope are two types of scopes in JavaScript that determine the visibility and accessibility of variables.

    • Block scope refers to the visibility of variables within a block of code enclosed by curly braces. Variables declared with 'let' and 'const' have block scope.

    • Function scope refers to the visibility of variables within a function. Variables declared with 'var' have function scope.

    • Object literals: var obj = { key: value };

    • Constructor functions: function ObjectName() { this.key = value; } var obj = new ObjectName();

    • ES6 classes: class ClassName { constructor() { this.key = value; } } var obj = new ClassName();

    • Object.create() method: var obj = Object.create(pr

  • Answered by AI
  • Q12. What are the differences between shallow copy and deep copy in JavaScript?
  • Ans. 

    Shallow copy only copies the references of nested objects, while deep copy creates new copies of nested objects.

    • Shallow copy creates a new object but does not create copies of nested objects, only copies their references.

    • Deep copy creates a new object and also creates new copies of all nested objects.

    • Shallow copy can be achieved using Object.assign() or spread operator, while deep copy can be achieved using JSON.parse(

  • Answered by AI
  • Q13. What will be the output of the following JavaScript code fragment: `const a; function test() { console.log(a); }; test();`?
  • Ans. 

    The code will throw an error because 'a' is declared but not initialized.

    • The code will result in a ReferenceError because 'a' is declared but not assigned a value.

    • Variables declared with 'const' must be initialized at the time of declaration.

    • Initializing 'a' with a value before calling test() will prevent the error.

  • Answered by AI
  • Q14. How can you use CSS to arrange elements in a row and column layout?
  • Ans. 

    CSS can be used to arrange elements in a row and column layout using flexbox or grid layout properties.

    • Use justify-content and align-items properties to align items in the main axis and cross axis respectively

    • For grid layout, use display: grid; and grid-template-columns or grid-template-rows to define the layout

  • Answered by AI
  • Q15. Have you utilized CSS preprocessors, and if so, which ones?
  • Ans. 

    Yes, I have utilized CSS preprocessors such as SASS and LESS.

    • I have experience using SASS to streamline my CSS workflow by utilizing variables, mixins, and nesting.

    • I have also worked with LESS to improve code organization and maintainability through features like variables and functions.

  • Answered by AI
  • Q16. If I have assigned different colors to an ID and a class and applied both to the same element, which color will be applied based on CSS specificity precedence?
  • Ans. 

    The color applied will be based on the specificity of the selector, with ID having higher specificity than class.

    • ID has higher specificity than class in CSS

    • Color applied will be based on the selector with higher specificity

    • Example: If ID selector has color red and class selector has color blue, the color applied will be red
