My preferred JavaScript coding style :3

gistfile1.js

// multiple vars
var fs = require('fs');
var net = require('net');

// no whitespace after function name
// no whitespace after `(` and before `)`, like real text
// whitespace before block scope, open in the same line
// camelCase function names
function foo(bar, baz) {
  // ident with 2 spaces
  // no whitespace after control structures (like a function call)
  if(bar) {
    // no whitespace for member access
    // semicolons
    console.log(bar[baz]);
    // whitespace after block scope
    // whitespace around operators
  } else if(1 > 2) {
    // omit whitespace to emphasize operator precedence
    console.log(3*4 + 5*6);
  } else {
    // single quotes
    throw new Error('qux!');
  }
  // omit brackets only if conditional is one-liner
  if(baz) return 'woof';
}

// CamelCase class names
function Awesome() {
  // Object literals, one property per line
  foo({
    bark: 8
  })
}

async.waterfall([
  // named anonymous functions
  // callback is cb
  function qux(cb) {
    // error is err
    doSomething(function(err, data) {
      cb(err, data);
    })
  },
  function baz(cb) {
    // align parameters when function call is long
    complicatedThing('foo',
                     'bar',
                     'baz');
    // group parameters when needed
    cp.exec([
      'prog',
      '-o', 'bar',
      '-m', 'baz',
      '--qux', '13', 'foo'])
  }
  // I'm not sure about identation for the function below...
], function(err) {
  console.log('done');
});
