What are some examples of using the pop method in JavaScript arrays?

Can you explain how the pop method works in JavaScript arrays?

Sure! The pop method removes the last element from an array and returns that element. If the array is empty, it returns undefined.

Can you give me some examples of using the pop method?

Of course! Here's a simple example: let arr = [1, 2, 3]; arr.pop(); // arr is now [1, 2] and it returns 3.

What happens if I call pop on an empty array?

If you call pop on an empty array, it will return undefined and the array will remain empty.

Are there any other methods similar to pop?

Yes, there's the shift method, which removes the first element of an array, and the splice method, which can remove elements from any position.
