Today, JavaScript is the basis of a large portion of all the world's software. Oliver has used the language as a "real" dev platform for at least 15 years and has a strong belief in totally dynamic JavaScript and its virtues. During this full-day workshop, he walks through his productivity preferences of object oriented as well as functional JavaScript, covers both client- and server-side JavaScript runtime environments, and explains everything about being safe, performant and productive without the need for explicit typing. You'll learn about module structures, precomputation, dependency injection and other application level patterns, promise chaining and how to make the best of JavaScript whether you intend to create full-blown application systems or whether you just need to understand code written by your your colleagues or your TypeScript compiler. The whole day is hands-on -- bring your laptop, follow along and take advantage of practice sessions!
