Modules: AMD versus CJS

amd_vs_cjs.js

//---------------------
// AMD

define(["foo", "bar", "baz"], function (foo, bar, baz) {
    return {
        func: function (...) { ... }
    };
});

//---------------------
// CJS/Node.js

var foo = require("foo");
var bar = require("bar");
var baz = require("baz");

exports.func = function (...) { ... };

exports.func is evil. Use module.exports = function () {}

I don't think the syntax differences are important. What is important: browsers require async and async is harder to use. Syntax is a side effect: browsers require async and async in JS requires callbacks. Hence AMD.
