As promised, I’m back to talk a bit more about objects.
I said there is another way to create objects, and that is using the Object Class (not really a class, but commonly called that way):

var myObj = new Object();
myObj.prop = “my property”
myObj.method = function(){

}

As you can see, it is really easy to create objects using the Object “class”. It is basically the same as writing objects using the literal notation.

One thing I’d have liked to see is usage of the prototype of the constructor function because that is what actually makes a difference between using the constructor and literal notation or Object(). Besides that, I think it is a really good introduction to OO Javascript.

I just scanned the article. No time to read it whole today, but I’ll soon. I just wanted to point out that theres is yet another way to create objects in javascript. I’ll comment more on that and some other things that I see are missing in the article.

I agree with Jeremy. I think you did a good job with the tutorial, covering areas people typically have trouble, but some of the fundamental parts are “hand-waved”. Remember that your audience is developers. If you are going to water down particular sections let them know!!

The part I found most frustrating was your explanation of “scope” and “this”. To be honest, you provide a good ballpark description to “get the jist of it” but you don’t indicate that there is more to it, or point to a resource where someone can learn it correctly in more detail. To put it in perspective, what is a developer to think when they use jQuery and “this” continually changes seemly magically for them?

In summary. Be honest/open about simplifications and point to external resources for full disclosure if it may benefit the readers. I can see that you put a lot of work into this article and I appreciate that (I know from personal experience as well). Keep on writing, hopefully we can improve the quality of your articles =)

You’re certainly free to spend your time however you want, but how do you expect to write effective and efficient code if you don’t know the language? What do you do when you encounter a bug that is caused by the lack of knowledge of the language?

It’s fine to use a library, but you’re only selling yourself short by being completely and totally dependent on the library.
