Correct: `Array.from()` (it’s a static method) Incorrect: `Array.join()` (doesn’t exist; it’s a prototype method) This patch uses the common `#` syntax to denote `.prototype.`.

### castArray
|
|
|
|
Casts the provided value as an array if it's not one.
|
|
|
|
Use `Array.prototype.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]
|
|
```
