What is the difference between array push and pop?

Can you explain the difference between array push and pop?

Sure! The push method adds one or more elements to the end of an array, while pop removes the last element.

Can you give me an example of how to use both methods?

Of course! For example, if you have an array let arr = [1, 2, 3];, using arr.push(4) will make it [1, 2, 3, 4]. Then, arr.pop() will remove 4, leaving you with [1, 2, 3].

Are there any differences in performance between the two?

Generally, both methods are efficient, but pop is often slightly faster since it only removes an element without needing to add anything.

Can these methods be used on other data structures?

push and pop are primarily used with arrays in JavaScript, but similar concepts exist in other data structures like stacks.
