Object Oriented Javascript best practices? [closed]

I’m finding myself coding a big project in Javascript. I remember the last one was quite an adventure because hacky JS can quickly becomes unreadable and I want this code to be clean.

Well, I’m using objects to construct a lib, but there are several ways to define things in JS, implying important consequences in the scope, the memory management, the name space, etc. E.G :

• using var or not;
• defining things in the file, or in a (function(){...})(), jquery style;
• using this, or not;
• using function myname() or myname = function();
• defining methods in the body of the object or using “prototype”;
• etc.

So what are really the best practices when coding in OO in JS ?

Academic explanations really expected here. Link to books warmly welcome, as long as they deal with quality and robustness.

EDIT :

Got some readings, but I’m still very interested in answers to the questions above and any best practices.
