JavaScript Essentials


Our JavaScript course will give you the key skills to hand-code, debug and tweak JavaScript, to bring interactive controls and functionality to your web pages and apps.

JavaScript is a mature scripting language, and is at the core of some of the most exciting and cutting-edge functionality available in your browser today.

Not only that, but JavaScript is a great way to learn about programming essentials such as event handling and procedures, loop statements and more.

There are many JavaScript frameworks upon which you can expand your skills and extend your apps from here - such as Node.js, ECMAScript, Angular, React and Ionic (the list goes on), but to get the most out of JavaScript it's vital to have a strong understanding of what's happening from the ground up.


Web Developers who need to get to grips with the fundamentals of client-side scripting using JavaScript, in order to improve the functionality of user interfaces, web forms, controls and so forth. Also suitable for people who want to go on to learn more about AJAX or jQuery.
