What is the instanceof operator in JavaScript?
I saw this in a blog post by John Resig, and didn't understand what does it means in regular JavaScript code (without that library).

Hi, could anyone tell me why this code won't compile?
public boolean isOf(Class clazz, Object obj){
if(obj instanceof clazz){
return true;
}else{
return false;
}
}
Why I can't pass a class variable to instanceOf?
Thanks in advance.
