### 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)
);
```
