Download node at nodejs.org and install it, if you haven't already.
npm install immutable-array-methods --save
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);
console.log('result', result);
// num() doesnt' return a new array if the values are unchanged
result = methods.map(input, function (num) {
return num % 2;
});
result = methods.move([1, 2, 3], 0, 1);
console.log('move()');
console.log('input is unchanged', input);
console.log('result', result);
