Luc (GitHub: pllee / luc, License: MIT, npm: luc) by Patrick Lorian Lee is a framework written in ECMAScript 5 designed to work with browsers and Node. It includes classes for working with arrays, dates, functions, events, and some high-level architectural tools.

For example, this is the composition API, which allows functionality to be added to classes while respecting the inheritance chain:

var C = Luc.define({  
  $compositions: {
    defaults: Luc.compositionEnums.EventEmitter,
    methods: ['emit']

var c = new C();

typeof c.emit  
typeof c.on  

Classes can be created with Luc.define:

var C = Luc.define({  
  init: function() {
    Luc.Array.each(this.items, this.logItems)

  logItems: function(item) {

var c = new C({items: [1,2,3]});  
var d = new C({items: 'A'});  
var e = new C();  

The array functions can be found under Luc.Array -- it has the kinds of methods you might be familiar with from libraries like Underscore. The method signatures are similar as far as I can tell: Luc.Array.findFirst([1,2,3, {}], {});.

Luc's source has JSDoc-style comments, a Grunt build script, and unit tests. It has no dependencies and is currently around 650 lines of code.


z.js (Source: z.js, License: MIT) is a tool for turning text into a binary code that uses zero width non-breaking spaces. That means you can create invisible messages that work in most modern browsers (including IE8+). It can even apply a password to the message so potential snoops must go through an extra level of misdirection.

There's even an ASCII mode where tabs and spaces are used instead of UTF8.


I really loathe making tables, yet almost every project seems to need them. I inevitably end up creating or finding a table generator that can turn data into suitable HTML tables. Tabler (GitHub: BrandwatchLtd / tabler, License: MIT) by Steve Mason is an AMD-friendly, Mocha-tested library for building dynamic tables. It takes an array then generates tables based on a "spec" -- a definition of the headers and properties to include in the output.
Usage looks like this:

var table = tabler.create([  
    {field: 'name', name: 'Name'},
    {field: 'apples', name: '# Apples'},
    {field: 'bananas', name: '# Bananas'}

    {name: 'Steve', apples: 2, bananas: 4},
    {name: 'Graham', apples: 1, bananas: 6},
    {name: 'Dan', apples: 9, bananas: 2},
    {name: 'Jon', apples: 5, bananas: 6}
