Beautiful Javascript. This is an example of what I think good Javascript formatting looks like (my style guidelines). Fork this and show me how you like it, or comment if I forgot anything.

example.js

// camel case variable names (no underscores)
// instance variables are nouns
var myArray = [1, 2, 3]; // space after commas
 
// title case for class names (class names should be nouns)
// space before bracket
function Widget() {
  // two spaces for indentation
  var parameterOne = 1;
  var parameterTwo = 2;
  doSomething(parameterOne, parameterTwo);
}
 
// space before and after "="
// camel case key names, unless matching a server side format
// single quotes for strings
var myObject = {
  myKey: 'value'
};
 
// space before and after parens
if (myArray.length === 0) {
  var x = 1;
} else { // else uses one line
  var y = 2;
}
 
// function names should be verbs
// space after params of function definition
logSomething = function(text) {
  return console.log(text);
};
 
 
// when passing objects, use a space after the key, and after the comma 
doSomething({ x: 2 }, { y: 3 });
 
//Use newlines to group logically related pieces of code. For example:
doSomething(x);
doAnotherSimilarThing(x);
 
doSomethingTotallyDifferent(y);

Glad to see my style choice matches the majority: http://sideeffect.kr/popularconvention/#javascript
