### 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]
|
|
```
