Can one call a function from itself?

Question

Can I do this:

function something(){

    for(x in y){
        if(x.toString() == "[object Object]"){
            something();
        }
    }

}

Yes. It's called recursion, and it's available in JavaScript. In your case, it would be infinite recursion, which would cause a stack overflow. Make sure your condition for whether it's called or not will actually change to avoid infinite recursion.
