+### castArray
+
+Casts the provided value as an array if it's not one.
+
+Use `Array.isArray()` to determine if `val` is an array and return it as-is or encapsulated in an array accordingly.
+
+```js
+const castArray = val => Array.isArray(val) ? val : [val];
+```
+
+```js
+castArray('foo'); // ['foo']
+castArray([1]); // [1]
+```
