array-unflat

The opposite of Array.prototype.flat() with depth = 1.

npm install array-unflat

Example

const unflat = require('array-unflat');

const arr = [0.2, 0.3, 0.5, -1.8, 2.9, 1.1];
console.log(unflat(arr));
console.log(unflat(arr, 3));

Output:

[ [0.2, 0.3], [0.5, -1.8], [2.9, 1.1] ]
[ [0.2, 0.3, 0.5], [-1.8, 2.9, 1.1] ]
