RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including @extra-entries/compare. Try it out:
const entries = require("extra-entries");
var x = [["a", 1], ["b", 2]];
var y = [["a", 1], ["b", 2], ["c", 3]];
entries.compare(x, y);
var y = [["a", 1], ["b", 2]];
entries.compare(x, y);
var y = [["a", 1], ["b", -2]];
entries.compare(x, y);
entries.compare(x, y, (a, b) => Math.abs(a) - Math.abs(b));
entries.compare(x, y, null, v => Math.abs(v));
