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.
