This is a really basic question really just to satisfy my curiosity, but is there a way to do something like this:

if(obj !instanceof Array) {

    //The object is not an instance of Array

} else {

    //The object is an instance of Array

}

The key here being able to use the NOT ! in front of instance. Usually the way I have to set this up is like this:

if(obj instanceof Array) {

    //Do nothing here

} else {

    //The object is not an instance of Array

    //Perform actions!

}

And its a little annoying to have to create an else statement when I simply want to know if the object is a specific type.
