this property

arguments property

Method invocation pattern

method: function stored as a property

this - object containing method

late binding

Sample 1

Function invocation pattern

this - global object [design mistake]

inner functions this: refers to global object

var that = this

Sample 2

Constructor invocation pattern

functions invoked with new prefix

this - new object created

no explicit return value - this is returned

hidden link to function's prototype

Sample 3

Apply invocation pattern

apply method• two parameters

o value for thiso array of parameters

this - first parameter of apply
