javascript function name, duplicates, good practices

[Jesus Angeles]

There is no concept for namespaces, e.g. java packages, in javascript, if I am not wrong.

Is there any good practices that we can apply to lower the possibility of same function names?

This will come up a lot once we start having big number of javascript codes, and/or use third-party libraries.

It's easy to create your own namespaces.

var Bear = {};
 
Bear.someFunction = function() {
  //do something wonderful
}
    

Functions are first-class objects in Javascript, so they can be created as literals and assigned as properties of other objects. This is the basis of object-oriented Javascript.

In the above example, I created a "namespace object" named Bear, and then created a function via a function literal and assigned it to the property named someFunction on Bear.

To call the function:

  Bear.someFunction();

Use OO JavaScript.

Define an object specific to what you are doing and use that as a "Namespace"

Thanks.

Thats an interesting construct. Is this a new feature? I just read a 2006 beginner's book on javascript and it doesnt mention it.

I see that scriptaculous uses it.

No, nothing new. But little has been written on using object-oriented Javascript.
