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-array/sort-on.min. Try it out:
const array = require('extra-array');
var x = [-3, -2, 1, 4];
array.sortOn(x, v => Math.abs(v));
var x = ['B', 'D', 'a', 'c'];
array.sortOn(x, v => v.toLowerCase());
