Is "this" the same as artist?

Hi,

Could someone please clarify with me if the word "this" is the same as "artist" in the following 3 lined piece of code...

function song(title, artist, duration){ Media.call(this, title, duration); this.artist = artist; }

So what i'm asking is if the word "artist" in the first line is the same as "this" in the second line.

The quick answer is nope. Let's look at the coding:

function song(title, artist, duration) { 
   Media.call(this, title, duration); 
   this.artist = artist; 
}

/*
In Media.call();  call() is a method.
You can invoke a function using the call() method.  The first argument is the 
object that will be used as the value of the this keyword. This allows you to set 
and control what the this keyword is instead of relying on how javaScript is 
designed to use the this keyword.
