interleave

Places values of an array between another. 🏃 📼 📦 🌔

array.interleave(x, y, [m], [n]);
// x: an array
// y: another array
// m: number of values from x (1)
// n: number of values from y (1)

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

var x = [1, 2, 3, 4];
var y = [10, 20, 30, 40];
array.interleave([x, y]);
// [ 1, 10, 2, 20, 3, 30, 4, 40 ]

var y = [10, 20];
array.interleave([x, y]);
// [ 1, 10, 2, 20, 3, 4 ]
