### compact
|
|
|
|
Removes falsey values from an array.
|
|
|
|
Use `Array.filter()` to filter out falsey values (`false`, `null`, `0`, `""`, `undefined`, and `NaN`).
|
|
|
|
```js
|
|
const compact = (arr) => arr.filter(Boolean);
|
|
// compact([0, 1, false, 2, '', 3, 'a', 'e'*23, NaN, 's', 34]) -> [ 1, 2, 3, 'a', 's', 34 ]
|
|
```
