Modern JavaScript Masterclass

2 Days
Online Duration
3 Days

This richly layered and comprehensive course provides the perfect framework in which to learn about JavaScript. Over the 2 days each student will take on-board detailed explanations of everything from the ground up to advanced contemporary ECMA Script development


It is expected that delegates will be familiar with Java, C#, Python or a similar programming language as well as show fluency in HTML.

Course Contents
