Introduction

JavaScript is a powerful object-oriented programming language, but unlike traditional programming languages, it uses a prototype-based OOP model, making its syntax hard for most developers to understand. In addition, JavaScript uses functions as the primary object, which may cause greater confusion for developers who are not familiar with the language. That is why we decided to introduce it as a brief preface, and it can also be used as a reference for Object-Oriented Programming in JavaScript.

It takes some time to adapt to prototype inheritance, but this is an important concept that must be familiar. Although the prototype inheritance model is often considered a weakness of JavaScript, it is actually more powerful than the traditional model. For example, it is easy to create a traditional model after you have mastered the prototype model.

ECMAScript 6 introduces a new set of keywords for implementation classes. Although the new designs seem very similar to traditional class-based development languages, they are not the same. JavaScript is still based on the prototype.

Conclusion

JavaScript has been developing for a long time. During this period, according to today's standards, some methods that should not be used are used by a large number of developers. According to ES2015, this situation is slowly changing. However, many developers still insist on using some old programming methods, which damages the relevance of their code. Understanding object-oriented programming methods and applying them to your JavaScript project make sense for writing sustainable code.

I hope this brief introduction will help you achieve this goal.
