The JavaScript prototype pattern is the most poorly designed aspect of the JavaScript language. Cross-browser prototype compatibility is a total headache too.

The JavaScript prototype pattern is the most poorly designed aspect of the JavaScript language. Cross-browser prototype compatibility is a total headache too. My solution: abstract away the headache. Use Underscore's extends function or take a look at how Prototype.js handles inheritance: http://prototypejs.org/learn/class-inheritance http://prototypejs.org/learn/class-inheritance . Both solutions are much more simple and do the same thing. Also, if you are going into a JavaScript interview, know the stupid prototype pattern, someone always asks about it.
