+### Random integer in range
+
+Use `Math.random()` to generate a random number and map it to the desired range, using `Math.floor()` to make it an integer.
+
+```js
+const randomIntegerInRange = (min, max) => 
+  Math.floor(Math.random() * (max - min + 1)) + min;
+// randomIntegerInRange(0, 5) -> 2
+```
