During this 3-day practical workshop, you will learn modern JavaScript language elements which combine many programming languages paradigms and have a lot of different uses. You will also find out what are the key elements of functional programming and the benefits of using them. This workshop is directed to both programmers that don’t know JavaScript yet, as well as to the experienced JavaScript developers who want to broaden their knowledge.
