Welcome to an exciting exploration of two fundamental data structures: Stacks and Queues! Remember, data structures store and organize data in a manner that is structured and efficient. Stacks and Queues are akin to stacking plates and standing in a line, respectively. Intriguing, isn't it? Let's dive in!

A Stack adheres to the "Last In, First Out" or LIFO principle. It's like a pile of plates where the last plate added is the first one to be removed. TypeScript uses arrays to create a stack, leveraging the push() method to add an element to the end of the array and the pop() method to remove the last element. These methods help implement the LIFO behavior, with type safety enforced through type annotations.

Let's explore this using a pile of plates.

The last plate added was removed first, demonstrating the LIFO property of a stack.

A represents the "First In, First Out" or FIFO principle, similar to waiting in line at the grocery store where the first person to arrive is the first to be served. In TypeScript, we can use arrays to achieve this behavior, using for enqueueing (insertion at the end) and for dequeueing (removal from the front).
