Beginning Object-Oriented Programming with JavaScript
3 days  (Instructor Led Online)  |  Web Development

Course Details


The purpose of this Beginning Object-Oriented Programming with JavaScript course is to cover all the new object-oriented features introduced in ECMAScript 2015 and show how to build large-scale web apps that promote scalability, maintainability, and reusability. It is ideal for development teams that are thinking of using JavaScript for full-stack web development so that they only need to worry about one language across the entire stack.

JavaScript is one of the most widely used programming languages in the world. Born as a simple glue between the user and HTML, it has evolved over the years and has acquired an increasingly important role in modern software development. Today, its scope is no longer just the web browser. Now, it also resides on the server, desktop PCs, mobile devices, and even embedded devices.

JavaScript has now become a language to create complex applications. Beginning Object-Oriented Programming with JavaScript course explains how to write robust and efficient code with JavaScript to create scalable and maintainable applications.

This course begins with a subtle refresher on objects. It teaches you how easy it is to define objects with the new ECMAScript classes. From there, we’ll fly you through some essential OOP principles, forming a base for you to get hands-on with encapsulation.

You’ll get to work with the different methods of inheritance. From there, we’ll move on to some advanced patterns for object creation, and you’ll get a strong idea of how to use interesting patterns to present data to users and to bind data. You’ll manage dynamic typing using various data types and get familiar with duck typing and polymorphism.

You’ll explore various presentations such as MVC and MVP, along with implementing data binding.

By the end of this course, you’ll discover whether JavaScript is asynchronous and learn to write asynchronous code using callbacks and events.

We specifically focus on object-oriented programming with JS in this course, so prior understanding of basic syntax is assumed.



For successful completion of this course, students will require the computer systems with the following:

  • Processor: 1.8 GHz or higher Pentium 4 (or equivalent)
  • Memory: 2 GB RAM
  • Hard disk: 10 GB
  • Projector
  • Internet connection



Most of the code provided in this course is not bound to a specific JavaScript runtime environment, so it could run in any JavaScript environment. For this course we will be using the following environment:

  • Chrome DevTools
  • Atom
