JB's JavaScript coding standards

standards.js

// File Names
// lowercase separated by dashes
// not underscores because Node uses dashes for require() 
//   so using dashes for file names keeps with that standard
// lowercase because not all OS have case sensitive file names

// RIGHT
application.js
some-cool-controller.js

// WRONG
Application.js
someCoolController.js
some_cool_controller.js

// Quotes
// Use double quotes over single quotes.
// Performance reasoning for single quotes is silly. 
// Double quotes match other languages more.
// HTML & JSON prefer double quotes. Following Twitter Bootstrap example.
// RIGHT
"Hello World"

// WRONG 
'Hello World'

// Declaring variables
// https://github.com/felixge/node-style-guide
// I concur with these points from the above link:
// Declare one variable per var statement, it makes it easier to re-order the lines. 
// Ignore Crockford when it comes to declaring variables deeper inside a function, 
// just put the declarations wherever they make sense.
// RIGHT
var keys   = ['foo', 'bar'];
var values = [23, 42];

var object = {};
while (keys.length) {
  var key = keys.pop();
  object[key] = values.pop();
}
// WRONG
var keys = ['foo', 'bar'],
    values = [23, 42],
    object = {},
    key;

while (keys.length) {
  key = keys.pop();
  object[key] = values.pop();
}
