Chapter 1. A Refresher of Objects
Any JavaScript programmer knows that almost everything in this scripting language is an object—from arrays to functions, from regular expressions to dates. We can say that what is not a primitive data type is an object. But, even the primitive data types such as numbers or strings have object wrappers, that is, they are accessible via objects. So, we can argue that objects are vital in JavaScript, and we need to learn the use of objects as best as we can in order to create better applications. One way, for example, to better use objects is applying the Object-Oriented Programming (OOP) paradigm.
However, before diving into principles and pattern of this programming approach, let's start this first chapter with ...
