How Does the pop() Function Work in Programming Arrays?

Learn how the pop() function removes the last item from an array and affects the array length in programming.

0 views

The `pop()` function removes the last item from an array and returns that item. This method changes the length of the array. In most programming languages that support it, `pop()` can be used on dynamic arrays. It's a simple and effective way to manipulate the contents of an array, especially when working with a stack data structure where you need to remove elements in a last-in, first-out (LIFO) manner.
