My Google-ing on this has been unsuccessful, so here's the question:
I am wondering if it is possible to add my own keywords to extend the JavaScript language in a given framework.
For example
Object1 extends Object2
in the code would result in executing this method
inherit(Object1, Object2)
Where inherit is a function that takes care of copying the prototype, adding the parent's constructor, etc..
Is this doable? If so, how ? If not, any other nice way of doing this?
Thanks.
It's not possible to add new keywords to JavaScript, no. You could create your own nice interface for creating classes though, perhaps drawing inspiration from one of the myriads of library, frameworks and toolkits out there already!
You can't add keywords to the language but everything is an object and everything can be extended with prototyping.
I wouldn't normally link to crockford but he actually has quite a decent coverage of this , which will afford you syntax of the form foo.inherits(bar); which is about as good as one could wish for. This is quite a common pattern.
