compare (original) (raw)

Compare two arrays (lexicographically).

Similar: compare, isEqual.

function compare(x, y, fc, fm) // x: an array // y: another array // fc: compare function (a, b) // fm: map function (v, i, x)

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

var x = [1, 2]; var y = [1, 2, 3]; xarray.compare(x, y); // → -1

var y = [1, 2]; xarray.compare(x, y); // → 0

var y = [1, -2]; xarray.compare(x, y); // → 1

xarray.compare(x, y, (a, b) => Math.abs(a) - Math.abs(b)); // → 0

xarray.compare(x, y, null, v => Math.abs(v)); // → 0
