• function and method names are camelCase
• private methods start with underscore

comments

every class or method should be commented. Ok. every class or method which is not clear should be commented

/**
 * Illustrates line wrapping for long param/return descriptions.
 * @param {string} foo This is a param with a description too long to fit in
 *     one line.
 * @return {number} This returns something that has a description too long to
 *     fit in one line.
 */
function method(foo) {
  return 5;
}

misc

• variable declaration:

var a = 'a'
  , b = null
  , c;

• we use semicolons (use jslint or similar to check)
