Frequently asked JavaScript questions in Interview| JavaScript Interview preparation #reactjs

In this short, I explain block-scoped variables in JavaScript and how var and let behave differently inside loops when used with setTimeout.
This is a very common JavaScript interview question that tests your understanding of:
Function scope vs block scope
How var is hoisted and shared across loop iterations
Why let creates a new binding for each iteration
How closures work with asynchronous functions like setTimeout
I also walk through what output you get with var, what output you get with let, and why that happens internally in the JavaScript engine.
