What you need to know about Object Oriented Programming

Nice article!

I disagree with this statement:

This paradigm is based around defining “Classes” which will initialize “objects”

OO is about objects, not classes.

There are ways to implement OO without using classes and JavaScript is a great example.

JavaScript, as described by ECMAscript specification, is an:

... object-oriented programming language for performing computations and manipulating computational objects within a host environment.

However, objects are not created by class instancing.

Even though ECMAScript includes syntax for class definitions, ECMAScript objects are not fundamentally class-based such as those in C++, Smalltalk, or Java.
