Flatten a nested array.
The nesting can be to any depth. If you pass shallow, the array will only be flattened one level.
- Small utility to flatten nested arrays.
- Free of TypeScript. 😄
Install with npm
$ npm install flat-util
Or unpkg
<script src="/proxy?url=https%3A%2F%2Funpkg.com%2Fflat-util%401.1.9%2Fumd%2Findex.js" />
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]]];| Like us a lot? Help others know why you like us! Review this package on pkgreview.dev | ➡ |  |
