Nice post about "this" in JS

Best part of the post:

When working with this, remember the following rules:

• It’s set based on how a function is called: new MyConstructor ormyObject.method() will refer to an instance, while this inside a function refers to the global context
• Strict mode causes this to evaluate to undefined instead of the global context inside functions
• this can be referenced by a variable, and self is the conventionally used name
