- Q2. What are promises in javascript
- Ans.
Promises are a way to handle asynchronous operations in JavaScript.
Promises represent a value that may not be available yet.
They can be in one of three states: pending, fulfilled, or rejected.
Promises can be chained together using .then() and .catch() methods.
They help avoid callback hell and make code more readable.
Example: fetch() returns a promise that resolves with the response object.

- Q1. Difference between let, var and const.
- Ans.
let, var and const are all used for variable declaration in JavaScript, but they have different scopes and behaviors.
let has block scope, var has function scope, and const is a constant that cannot be reassigned.
let and const are hoisted but not initialized, while var is hoisted and initialized with undefined.
Using const for objects and arrays does not make them immutable, only the reference is constant.
