JavaScript Object-Oriented JavaScript (2015) Prototypal Inheritance Building the Movie Object

Posted by Ang Kee Hian

What happens if we don't use prototypal inheritance for this?

For this task, how will the code be like if we don't use prototypal inheritance? How difficult will it be if we were to add another object (for e.g., tv series) without using prototypal inheritance?

Would greatly appreciate it if someone could explain, in simple terms, the benefits of using prototypal inheritance.

Thanks!

Methods added to the prototype become immediately available to all existing instances of an object class. Those added to the constructor will only be available to new instances created later.

Also, all instances share the same prototype code (saving memory), but any code created in the constructor will be replicated in each instance.
