JavaScript, Math, Random · Oct 22, 2020

Generates an array of n
random integers in the specified range.
- Use
Array.from()
to create an empty array of the specific length. - Use
Math.random()
to generate random numbers and map them to the desired range, usingMath.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 ]
