+Initializes and fills an array with the specified values.
+
+- Use `Array.from()` to create an array of the desired length, `Array.prototype.fill()` to fill it with the desired values.
+- Omit the last argument, `val`, to use a default value of `0`.
+
+```js
+const initializeArrayWithValues = (n, val = 0) =>
+  Array.from({ length: n }).fill(val);
+```
+
+```js
+initializeArrayWithValues(5, 2); // [2, 2, 2, 2, 2]
+```
