what are the characteristics that indicate that this Function is a class, and same thing for methods?
for example if an object was created from a function using new keyword this indicate that this function is a class.
function foo()
{}
var x = new foo();
am looking for other indicators/characteristics of class and a method.
JavaScript doesn’t use the class/method techniques that lower languages have. Instead, prototyping and closure can be used to simulate those aspects.
You’ll get a pretty good run-down of the techniques at this [url=“http://javascript.crockford.com/private.html”]private members page.
Just because those aspects can be simulated though, doesn’t mean that they are the best way in JavaScript to achieve the end result.
