Ans. 
Error handling in JavaScript involves using try-catch blocks, throwing errors, and using error objects.

• 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.
