Part 2. of the OOP in JavaScript. Today we will show some more advanced examples. OOP in JavaScript — techniques For a good start, let’s take a closer look at arrays. Arrays as objects A simple array, e.g.: can be written in a concise form: And certainly we can operate on arrays in the same […]

Welcome to the first part of the articles about object-oriented programming (OOP) in JavaScript. It is actually necessary to explore of the language secrets. Object-oriented programming in JavaScript JavaScript is an object-oriented language, although there is a lack of certain elements typical for object-oriented languages, at least in the current implementations of JavaScript.
