+### Initialize array with values
+
+Use `Array(n)` to create an array of the desired length, `fill(v)` to fill it with the desired value.
+You can omit `v` to use a default value of `0`.
+
+```js
+var initializeArray = (n, v = 0) =>
+  Array(n).fill(v);
+```
+
 ### Random number in range
 
 Use `Math.random()` to generate a random value, map it to the desired range using multiplication.
