### initializeArrayWithValues
Initializes and fills an array with the specified values.
Use `Array(n)` to create an array of the desired length, `fill(v)` to fill it with the desired values.
You can omit `val` to use a default value of `0`.
```js
const initializeArrayWithValues = (n, val = 0) => Array(n).fill(val);
```
```js
initializeArrayWithValues(5, 2); // [2,2,2,2,2]
```
