Object-Oriented JavaScript

Objects in JavaScript encapsulate both data and functionality. You'll create, access, and modify objects to build a solid foundation for object-oriented programming.

Functions are one of most important data structures. Learn what a "first-class function" is, learn about scope, dig into closures, and use immediately-invoked function expressions for private state.

Creating objects individually isn't sustainable. Learn how to create similar objects with ease using Classes. You'll also learn how object inheritance works through Prototypal Inheritance.

Discover object-oriented design patterns that can be used to create an object -- all without involving its prototype. What's more: you'll also learn how to implement private properties in objects.
