JavaScript Concepts
I started learning JS for a while and i cant understand some concepts. If are you learning JS and fell a little lost, check it out: http://bolinfest.com/javascript/misunderstood.html
Things like:
- JavaScript Objects are Associative Arrays whose Keys are Always Strings;
- There are Several Ways to Look Up a Value in an Object;
- Single-quoted Strings and Double-quoted Strings are Equivalent;
- There are Several Ways to Define an Object Literal;
- The "prototype" Property is Not the Prototype You are Looking For(better explanation i saw);
- The Syntax for Defining a Function is Significant;
- What "this" Refers to When a Function is Called;
- The "var" Keyword is Significant;
- Block Scope is Meaningless
Probably, you see this topics in other place but, to me, the way how is explained generated a lot of "A-ha" moments.

You should also check out http://bonsaiden.github.io/JavaScript-Garden/ , it's another collection of JavaScript's "confusing" parts.
I really like this type of content. Things like:
function Foo(){}
Foo.bar = 1;
Foo.bar; // 1And this is what i`m talking about everything is a object in JavaScript.
