For removing data from an array using
JavaScript we can, among other things,
use built-in methods like pop(), shift()
and splice();

//Remove last element
arr.pop();

/*
We previously used splice() to add
elements to an array. If we do not
specify elements that we want to add,
but only specify starting position and
number of elements, those elements will be
removed from an array, and returned as
an array.
