  • 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.
