In this video, we break down Stack Implementation from the absolute basics. If you don’t understand what a Stack is, moving further in DSA becomes tough. so we start with a simple, real-life explanation.

You can learn DSA by watching part 1 - https://youtu.be/93J3Y-dmP3I

You’ll see how Stack works using the LIFO (Last In First Out) rule and how to implement it manually using JavaScript.

We create an empty array, track the top pointer, perform push() and pop() operations, and understand how each step translates inside memory.
By the end of this video, you'll know how the Stack works inside code, how values move, and how to build your own implementation from scratch.

This video breaks it down visually, logically, and in the simplest possible way. If you’re learning DSA for interviews, this video will help you build a strong foundation.
