- Q1. Difference between useMemo and useCallback ?
- Ans.
useMemo is used to memoize a value, while useCallback is used to memoize a function.
useMemo is used to memoize a computed 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.
- Q2. How we do error handling in js ?
- Ans.
Error handling in JavaScript involves using try-catch blocks, throwing errors, and using error objects.
Use try-catch blocks to catch errors and handle them gracefully
Throw errors using the throw keyword to indicate when something goes wrong
Use error objects like Error, SyntaxError, TypeError, etc. to provide more information about the error
Handle asynchronous errors using promises and the .catch() method
- Q3. What is Promises ? Write a Polyfill of Promise.all()
- Ans.
Promises are objects representing the eventual completion or failure of an asynchronous operation.
Promises are used to handle asynchronous operations in JavaScript.
Promise.all() takes an array of promises and returns a single promise that resolves when all of the input promises have resolved.
A polyfill for Promise.all() can be implemented using a combination of Promise and Array.prototype.reduce().
