• 19.1.1 The Object Constructor

The Object constructor is designed to be subclassable. It may be used as the value of an extends clause of a class definition.

• 19.2.1 The Function Constructor

(...) When Function is called as a function rather than as a constructor, it creates and initializes a new Function object. Thus the function call Function(…) is equivalent to the object creation expression new Function(…) with the same arguments.

The Function constructor is designed to be subclassable. It may be used as the value of an extends clause of a class definition. Subclass constructors that intend to inherit the specified Function behaviour must include a super call to the Function constructor to create and initialize a subclass instances with the internal slots necessary for built-in function behaviour. All ECMAScript syntactic forms for defining function objects create instances of Function. There is no syntactic means to create instances of Function subclasses except for the built-in Generator Fun

Anotações da palestra feita pelo Leo Balter na QCon do Rio em 2015 sobre o Ecossistema de produção e lançamento de novidades e especificações do JavaScript.

• Functions are first-class citizens, syntax resembles Java, inheritance is prototypal, and (+””) equals zero.
• O JavaScript foi criado em 10 dias pelo Brendan Eich em 1995.
• Quando falamos sobre o JS, nós falamos sobre muitas outras coisas que orbitam em volta da linguagem em si. Como o DOM, NodeJS ou o asm.js
• Hoje ele passa por um caminho de evolução. Hoje ele ainda é feito por um grupo chamado Ecma. Que é como o ISO, onde eles criam padrões e o JS é feito se baseando nessa padronização.
• O ES6 vem com muitas novidades. Algumas coisas principais: promises, generators, proxies, reflect, arrow functions, rest parameters, default parameters, class, Template
• O ES7 vai trazer outras funcionalidades como async, SIMD, async generators
• O ES7 pode desembarcar em 2016. Não vai ser tão agressivo quanto o ES6, mas a ideia é trazer as novidades em uma velo

Follow instructions on Mozilla Wiki or TL;DR:

$ hg clone http://hg.mozilla.org/mozilla-central spidermonkey

Or use git from the GitHub mirror.

The following command avoid clonning the whole repo, but the last commit reference and the HEAD branch

The idea is to have nginx installed and node installed. I will extend this gist to include how to install those as well, but at the moment, the following assumes you have nginx 0.7.62 and node 0.2.3 installed on a Linux distro (I used Ubuntu).

In a nutshell,

1. nginx is used to serve static files (css, js, images, etc.)
2. node serves all the "dynamic" stuff.

So for example, www.foo.com request comes and your css, js, and images get served thru nginx while everything else (the request for say index.html or "/") gets served through node.

3. nginx listens on port 80.
