Popping and Pushing

When you work with arrays, it is easy to remove elements and add new elements.

This is what popping and pushing is:

Popping items out of an array, or pushing items into an array.

Popping

The pop() method removes the last element from an array:

const fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.pop(); // Removes "Mango" from fruits

Try it now

The pop() method returns the value that was "popped out":

const fruits = ["Banana", "Orange", "Apple", "Mango"];
let x = fruits.pop(); // x = "Mango"

Try it now

The push() method adds a new element to an array (at the end):

const fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.push("Kiwi"); // Adds "Kiwi" to fruits

Try it now

The push() method returns the new array length:

const fruits = ["Banana", "Orange", "Apple", "Mango"];
let x = fruits.push("Kiwi"); // x = 5

Try it now
