# Generate a JavaScript array of random integers in a given range

We've previously covered how to generate a random integer or number in a given range. But how about generating an entire array of integers in a specified range?

As you might expect, this is just a matter of **repeating the process** for generating an integer in the given range. You can use `Array.from()`

to create an **empty array of the specific length** and then use `Math.random()`

to generate **random numbers** and map them to the desired range, using `Math.floor()`

to make them integers.

const randomIntArrayInRange = (min, max, n = 1) => Array.from( { length: n }, () => Math.floor(Math.random() * (max - min + 1)) + min ); randomIntArrayInRange(12, 35, 10); // [ 34, 14, 27, 17, 30, 27, 20, 26, 21, 14 ]
