Prototypes and Inheritance in JavaScript

Forget everything you know about object-oriented programming. Instead, I want you to think about race cars. Yes – race cars.

That's the intro for my latest article @ Script Junkie - Prototypes and Inheritance in JavaScript. I hope you enjoy reading it.

Scott, nice article. javascript has always been an enigma to me. jquery made javascript easier, but it was still a black box operation. your article on prototypes helps me understand what the core javascript language is capable of. which demystifies some of javascripts "magic".

Great article! I've read others on this topic that haven't really helped me to understand the subject as well as yours did. Thanks! =)

So __proto__ and prototype are not the same? That right there clarified a lot for me. Thx for the article.

Nice article! But can you also explain why prototype and __proto__ can't be the same? The way you explain it makes it simple to understand, but why on earth do you both know prototype AND _proto__???

@Christof: Yes. To be honest, I didn't understand this fully for a number of years.

@Doeke: How did I know about __proto__ and prototype? By reading the spec again :) www.ecma-international.org/.../Ecma-262.htm
