Installation

Download node at nodejs.org and install it, if you haven't already.

Usage

var methods = require("immutable-array-methods");

var input = [1, 2, 3];
var result = methods.pop(input, 4);
console.log('pop()');
console.log('input is unchanged', input);
console.log('result', result);

result = methods.splice(input, 1, 1, 'foo');
console.log('splice()');
console.log('input is unchanged', input);
