Song.prototype = Object.create(Media.prototype) question

The relevant rhetorical question here is, "How do you make prototype-based inheritance happen in JavaScript?" Any object created by the Song constructor will have Song as it's prototype, but then how do you express that Song has Media as it's prototype? One of the standard ways is through Object.create()

I like to think that ineritance will bring every element from the fathers constructor to the childs constructor. In this case, it will bring the Media attributes to the Song constructor. If you have any methods inside the constructor those methods will be available to the children as well. However, when you use prototypes to define methods they are not inside the constructor`s curly brackets, and for that reason you must create the association between parent and children using a different command, whic is the Object.create().

Hi Seth and Andre, thanks for you explanations, still unsure why we need Song.prototype = Object.create(Media.prototype) ; Did we not do that with call()? What do you think of this statement?

Using call() is to share the properties and methods from one object constructor to another BUT you still need to set up a prototype chain for the js interpreter to read and link the object constructors together
