Common Object Patterns

Function argument patterns

• missing arguments in a function call are undefined
• additional arguments passed to a function call that are not defined as parameters are available from the arguments object that is available in all functions and is accessible like an array
• e.g. flexibility of the default jQuery constructor which is implemented as a single function body

Chaining

• useful for creating flent APIs for working against a mutable object. Designed around returning the source object. Also common in .NET LINQ
• every function execution has an implicit return value undefined
• capture the this object if the caller isn't trusted

• NB. delays < 4ms will bumped to 4ms
• Timers won't start until the outer-most function is finished

Timer Overview

• consider the timer stack
