What Are JavaScript Array Methods: pop() vs push() vs shift() vs unshift() (Cheat Sheet Included)

With JavaScript arrays, you can store multiple values under one variable. One way to modify that information is by changing the variable it is stored on's value, but that will change the entire array. What if you just wanted to add/remove information at the start or at the end of an array? With JavaScript array methods, you can!

pop()

Removes an element at the end of an array.

push()

Adds new element(s) to the end of an array.

shift()

Removes an element at the start of an array.

unshift()

Adds new element(s) to the start of an array.

TL;DR: pop() removes an element at the end of an array. push() adds new element(s) to the end of an array. shift() removes an element at the start of an array. unshift() adds new element(s) to the start of an array.
