Swap position of two items in array without changing the state of the passed array.

$ npm install swap-array --save

import SwapArray from 'swap-array';

var SomeArray = ['thats','cool','dude'];

SwapArray(SomeArray, 0, 2);
// ['dude','thats','cool'];

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.

Just import it usually but attend the default prop

var SwapArray = require('swapt-array').default;
