Though some are good suggestions for writing maintainable codes, I do not see a lot of opportunities to improve javascript from this. The pieces I would like to have are a) optional arguments and b) strict type checking. They are actually syntactic sugar in a way, because you can get the same effect using typeoff function. But restriction to 80 characters... would be definitely recommended as coding practice, but never be forced by the language!
