JavaScript Fundamentals

2 days / 14h

Course overview

This training covers the fundamentals of the JavaScript language. These basics are mandatory for the development of backend or frontend applications in JavaScript.

JavaScript is a lightweight, interpreted, object-oriented language with first order functions. It is better known as a scripting language for web pages, but is used in many environments other than browsers, for instance with Node.js. It is a dynamic, multi-paradigm, prototype-based scripting language that supports object-oriented, imperative, and functional programming styles.
