Places values of an array between another. :package: :smiley_cat: :running: :vhs: :moon: :scroll: :newspaper: :blue_book:

Similar: interleave, intermix, interpolate, intersperse.

This is part of package extra-array.

array.intermix(x, y, [m], [n], [s], [t]);
// x: an array
// y: another array
// m: number of values from x (1)
// n: number of values from y (1)
// s: step size for x (m)
// t: step size for y (n)

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

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

array.intermix(x, y);
// [ 1, 10, 2, 20, 3, 30, 4 ]

array.intermix(x, y, 2);
// [ 1, 2, 10, 3, 4 ]

array.intermix(x, y, 1, 2);
// [ 1, 10, 20, 2, 30, 10, 3, 20, 30, 4 ]
