How do inherent prototypes work?

You might not think this question applies to you, especially if you come from a classical background. But if you use objects, functions, or arrays, you’re probably already using prototypes, and can benefit from learning the logic behind them.

This course explores the mechanics of inheritance in JavaScript by showing how prototypes work as chained references to other objects. Learn to take full advantage of prototype shortcuts to make your work simpler and faster…and debug them if you hit a snag.

We’ll explore:

how to manipulate prototypes to work like traditional classes
how polymorphism and factory functions can be used within JavaScript
how the class, new, and this keyword work and how to use them
using the instanceof, Object.create, and Object.getPrototypeOf functions to explain why objects have the properties that they do
Develop the knowledge needed to use inheritance for faster, better, bug-free code.
