### randomIntWithLengthInRange
|
|
|
|
Returns a random integer in the specified range and length.
|
|
|
|
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 randomIntWithLengthInRange = (len, min, max) =>
|
|
Array.from({ length: len }, () =>
|
|
Math.floor(Math.random() * (max - min) + min)
|
|
);
|
|
```
