nor-array

Optimized Array Utility Library

Installation

Install using NPM: npm install nor-array

Example Usage

var ARR = require('nor-array');

var a = [1, 2, 3, 4];

ARR(a).forEach(function(v) {
	console.log(v);
});

Our implementation is about 50% faster than the standard Array.prototype.forEach().

Compatibility with standard Array methods

Our implementations are not fully compatible with ECMAScript implementations of Array operations.

Most notably because our implementation expects:

• Array is a dense (NOT sparse -- there must be no holes!)
• Assumes that indexes are between zero (0) and array.length: 0 <= i < array.length
• Does not support thisArg, call o.callback.bind(o) instead
• The array indexes do not change while our .forEach() is running

This assumption is the reason why it is faster.
