Package Exports

swap-array

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (swap-array) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Swap Array

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

Install

$ npm install swap-array --save

Usage

// Import with ES6
import SwapArray from 'swap-array';

// Import with ES5
var SwapArray = require('swap-array').default;

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

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

// and 'SomeArray' is still:
// ['thats','cool','dude'];

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.
