wow.. very direct, yet clear explanation! I’ve read a few articles regarding classes in JS, but this is the best one mainly because you try to distinguish that it is not a class, but a constructor function… It definitely helps me understand JavaScript a bit more instead of (subconsciously) understanding it through my C#/Java hat…

Hey Roman, yes you can create objects that way. I'm more interested in creating classes. A class is a description of an object, something that tells JavaScript how to create an object (what properties, methods, etc. is has). An object is an instance of a class, and an object instance is exactly what you've created in your example. That's a fine way to do it, but it isn't re-usable. In other words, if you wanted to create an object for jane, you'd have to code the entire object again.

Hi, thanks for great screencasts.
Here it is the my way of creating new objects

var joe = {
firstName : ‘Joe’,
lastName : ‘Blow’,
getFullName : function() {
return (this.firstName + ‘ ‘ + this.lastName);
}
}
