Understanding JavaScript’s Prototypal Inheritance

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:

Develop the knowledge needed to use inheritance for faster, better, bug-free code.
