List Object's built-in Properties

Question

Is there a way for me to loop over a Javascript Object\'s built-in properties?

for...in gets me close to where I want to go, but \"A for...in loop does not iterate over

No you can't list object's built in properties. But you can refer to the implementer's reference. For example, to know all the methods and properties of Math object implemented on firefox, you'll use Firefox's Javascript Math Reference: https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Math
