@Raizdecimal "Someone please tell him javascript ain't supposed to be Java." I couldn't agree more. He kept calling certain things "problems" where in fact the problem was that he expected JS to behave like Java. His "workarounds" are actually the way it's supposed to be done in JS. I could say the same thing about Java, calling the massive code just to create a binding a problem ... but I don't because there's a reason why it's done that way in Java, & a reason why JS is done differently.

"if you think of a function as a class, then __proto__ is on the instance and prototype is on the class" I think that's what he meant by saying only functions have prototypes ... all objects have prototypes but only functions requires you to associate the prototype.__proto__ with the .prototype of the class. I think he spent way too much time of __proto__ since the "new" constructor takes care of it for you and it's better practice to avoid __proto__ due to dependencies.

No, you're right that "this" isn't always "window", but it is the root environment variable whatever that is. For a browser it's windows. for server js frameworks it's "process" or "server" etc ... depending on the framework.

Strange. He talks about "__proto__" and "prototype". I've been reading JavaScript: The Definitive Reference (O'Reilly, 2007) and it does not mention "__proto__" at all. It explains that "prototype" is a property of ALL objects; whereas Misko states in the video that "prototype" is only defined for functions. In reading "JavaScript: The Good Parts", page 21, the first sentence under the heading "Prototype" says "Every object is linked to a prototype object from which it can inherit properties"

Unlike other videos of the Google tech talks I have seen so far, this one was boring. But thanks for sharing the knowledge anyway.

Hello there, that is a good point. I was thinking the same way, even though I am new to JavaScript, but I know many programming laguages.

spamero2 Says:
I think one thing missing when explaining the Function Closures was that the function will remember its environment in which they were defined. So the function binds to its scope at the moment of definition rather then to the current variables and their values found in the scope during execution. That's why the counter and prefix behave little bit like static variables. I think this makes understanding closures bit more easier... unless I mixed up something terribly
