var SwapArray = require('swap-array').default;
var SomeArray = ['thats','cool','dude'];
SwapArray(SomeArray, 0, 2);

`Does it change the passed array?
Nope, before it changes the positioning we clone the passed array and return just the new instance. Ideal for e.g. some redux-reducer where it's not allowed to change an existing state. If you want that the origin-array changes his state checkout the array-swap repo from Marko Jankovic.Benchmark
