LEARNING OBJECTIVES
- Identify core OOP concepts and how they apply to JavaScript objects and ES6 improvements
- Create and manipulate objects using literals, constructors, Object.create, and property access patterns
- Implement methods using this, and use getters/setters to manage property access and updates
- Build reusable object blueprints with constructor functions, instances, and shared prototype methods
- Apply data encapsulation in ES5 and ES6 using local variables with controlled get/set access
- Implement inheritance via prototype chains, Object.create/call, and ES6 extends/super
- Override inherited methods and extend classes with mixins to share behavior beyond inheritance

ABOUT THIS COURSE
Learn to write cleaner, more modular, and more scalable code in JavaScript by gaining mastery of Object Oriented Programming (OOP).
You'll start with the basics of object-oriented programming and build up to more advanced concepts such as prototypal inheritance, prototype chaining, method overriding and mixins. Along the way, you'll learn how each concept applies to JavaScript's sometimes unique way of handling things. You'll also see how various JavaScript features make it particularly convenient for OOP, with particular emphasis on changes introduced in ES6.
This course is filled with hands-on coding challenges, playgrounds, snippets, and illustrations to keep things interactive.
