Please, please don't spread this "object factory" pattern any further than it's already gone. It's an incredibly inefficient way to do OOP in JavaScript. Every time you create a new instance of a Developer, you redefine every single function. This makes instantiation far slower than it would be if you used prototypes, and leaks memory like crazy: N Developers means N copies of each function. So, first, it's slow -- take this test: https://gist.github.com/459112 https://gist.github.com/459112 Webkit: http://tinyurl.com/2csgzez http://tinyurl.com/2csgzez Firefox: http://tinyurl.com/29wd2ms http://tinyurl.com/29wd2ms And second, the memory use. Take a moderately-sized class, with ten member functions. The last time I benchmarked it in Chrome, using real prototypes, it takes a little under 32 megabytes of RAM to create a million instances of it. Try to create a million instances using the pattern you have above, and it spins the browser for minutes, and eats up 368 megabytes of RAM. IE just crashes. If you're doing OOP in JS -- please use prototypes as Eich intended...
