Javascript

[as4s1n]

I've been experimenting with javascript a little bit. I stumbled upon the Prototype object. I don't understand it. I know you give a custom property to it when using it but i don't understand how it works and what it does by doing that...

Please help

Prototypes provide an inheritance mechanism, like parent classes in other OO languages. When you access a property that isn't defined on an object, it checks that object's prototype, and then the prototype's prototype &c, just like checking base instances in other languages. Numerous pages describe the prototype property--try "Object Oriented Programming in JavaScrip" by Mike Koss.
