the : in javascript/json

[NuJoizey]

i've got a function that looks like this, but I really only have a vague understanding what it's doing. I think that it is JSON, but can somebody either explain to me what is happening in javascript formatted like this or point me towards a useful tutorial that I can read - i've read some similar things on the web, but nothing that seems to address this specific syntax:

   name: function(doSomething, e) {
        if (condition) {
            doStuff();
        }
        
    },

What does the colon after name denote, and why is there a comma at the end?

Thanks for considering my question.

Uncommitted, except to looking good. Constantly judging.

that looks like json, at least part of json. wikipedia is a good primer (

http://en.wikipedia.org/wiki/JSON).

here is another example

var me = {
  displayInfo: function(){
    alert(this.firstName + "(" + this.age +")");
  },
  firstName: "jason"
};
me.age = 30;
me.displayInfo();

[tt]{}[/tt] creates an object. we assign that object to [tt]me[/tt]. we create the object with 2 members. [tt]displayInfo[/tt] and [tt]firstName[/tt]. because js is dynamic we add another member, [tt]age[/tt], later (next line). finally we call [tt]displayInfo()[/tt] which shows a message box with the members we defined.
