Array pop()

JavaScript Array pop() Definition

The pop () method removes the last element of an array. And define a new array. So this method changes the sequence (length and elements).
pop () does not perform properly when applied regularly to non-sequence arrays. If we apply pop () in an empty array, it returns the “undefined” value.

Syntax:

array.pop()
