Small utility to flatten a nested array
Flatten a nested array.
The nesting can be to any depth. If you pass shallow, the array will only be flattened one level.
Install with npm
$ npm install flat-util
Or unpkg
<script src="https://unpkg.com/flat-util@1.1.9/umd/index.js" ></script>
Check out the unit tests on CodePen.
const flatten = require('flat-util');flatten([1, 2, [3, 4]]);//=> [1, 2, 3, 4]flatten([1, [2], [3, [[4]]]]);//=> [1, 2, 3, 4];flatten([1, [2], [3, [[4]]]], true);//=> [1, 2, 3, [[4]]];
