How to add or remove an element at the end of an array

Link to code snippet: GitHub

Let's begin with an array of colors:

const colors = ['red', 'blue', 'green']

We can add the color yellow to the end of our array:


Now, our array contains four different colors:

console.log(colors) // 4

We can also push multiple elements at the same time:

colors.push('orange', 'gray', 'black')

Now, we have a total of seven colors in our array:

console.log(colors) // 7

If we want to remove elements from the end of the array, we can use the Array.pop() method:


Finally, we're left with an array containing only six elements:

console.log(colors) // [ 'red', 'blue', 'green', 'yellow', 'orange', 'gray' ]
