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/move-within-update. Try it out:
const array = require("extra-array");
var x = [1, 2, 3, 4, 5, 6];
array.moveWithin$(x, 0, 1, 3);
x;
var x = [1, 2, 3, 4, 5, 6];
array.moveWithin$(x, 6, 3, 5);
