Description

"- the use of classes … is the source of a number of complications. This paper discusses prototypes as an alternative to classes … In a prototype-based language, copying rather than instantiation is the mechanism provided to the user for making new objects."

This is a line from a 1986 research paper discussing prototypes as an alternative to classes. Did you know that JavaScript is a prototype-based language and does not need classes? Did you know that JavaScript's Object-Oriented system is actually simpler than classes?

Unfortunately, due to the language being marketed as "Java's little brother", something called the "constructor pattern" was designed as a way to for the language to "look like" class-based Java. The decision to conceal JavaScript's true identity as a prototype-based language in favor of something that looked like half-baked classes has led to widespread confusion among developers that lives to this day.

In this course, we will explore JavaScript's true identity as a prototype-based language and look at different ways of doing OOP in JavaScript. We don't ignore classes or constructors - we will study them deeply and learn how they are abstractions over a prototype-based system and learn how to effectively utilize them.

In this lesson, we will learn how to write effective, maintainable and robust object-oriented code using JavaScript.

Who this course is for:

Beginning and intermediate JavaScript developers.
Advanced JavaScript developers: Many advanced developers I know are unfamiliar with OO secrets of JavaScript
