JavaScript Developer Course Overview

JavaScript is one of the most popular and commonly used programming languages today. Not only is it the language of the web and front-end frameworks like Angular and React,but it can now be used to build anything (front-end,back-end,or otherwise) thanks to runtimes like NodeJS.

This course is designed to provide delegates with the knowledge and skills necessary to build modern JavaScript apps. It further serves to set the delegates on course to dive into one of the many JavaScript frameworks. Delegates will learn about everything from variables,functions,and program flow,to functional and asynchronous programming,and managed apps.

Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.

NB: This course assumes ES6 as the baseline specification for JavaScript. This is because ES6 is now widely supported.

Course Objectives

This course aims to provide delegates with the skills and knowledge necessary to write core JavaScript code,exploit an understanding of the DOM and event handling to make web pages dynamic and interactive,and to build modern,managed JavaScript applications that exploit modern syntax. Delegates should be able to devise object-oriented and functional solutions to problems,and deal with asynchronous tasks such as IO.
