Returns an array of n random integers in the specified range.
|
|
|
|
- Use `Array.from()` to create an empty array of the specific length, `Math.random()` to generate a random number and map it to the desired range, using `Math.floor()` to make it an integer.
|
|
|
|
```js
|
|
const randomIntArrayInRange = (min, max, n = 1) =>
|
|
Array.from({ length: n }, () => Math.floor(Math.random() * (max - min + 1)) + min);
|
|
```
|
|
|
|
```js
|
|
randomIntArrayInRange(12, 35, 10); // [ 34, 14, 27, 17, 30, 27, 20, 26, 21, 14 ]
|
|
```
