## Introduction

In JavaScript, we may wish **to get a random value from an array.** In this post, we'll look at how to do it.

## How to get a random value from a JavaScript array

To get a random value from a JavaScript array we can use `Math.floor()`

and `Math.random()`

functions:

In the following example, we use the `Math.random()`

function to get a pseudo-random number between 0 and 1. Then we multiply that value by `array.length`

to get a random value no greater than the size of the array. Finally, we used `Math.floor()`

that rounds down a given number.

The `random`

variable contains a random index of `frontbackend`

array.
