 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`.
+- 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(n).fill(val);
+const initializeArrayWithValues = (n, val = 0) =>
+  Array.from({ length: n }).fill(val);
 ```
