Mastering JavaScript Object-Oriented Programming

Course Description

This course is designed to help new programmers learn popular Object-Oriented programming (OOP) principles and design patterns to build robust apps and implement Object-Oriented concepts in a wide range of front-end architectures using JavaScript. It covers the new features introduced in ES6 and shows participants the first steps in how to build large-scale web apps and build apps that promote scalability, maintainability, and reusability.

Duration: 5 days


No specific pre-requisites. The course is suitable for participants not familiar with OOP or for programmers who have not done any structured training on JavaScript.
