Are you eager to write more robust, error-free code and leave pure JavaScript behind? Then my TypeScript Simplified workshop is the perfect starting point. Over the span of two days, I'll introduce you to TypeScript's key concepts, all while providing hands-on experience through practical exercises.

Target audience and requirements

This workshop is aimed at developers who want to learn TypeScript from scratch. Basic JavaScript knowledge is required, besides that no previous knowledge is necessary. The workshop will be taught without focusing on a specific framework or library, but rather on the language itself. As usual, combining workshops is possible and recommended, in case it is planned to e.g. learn Vue.js and TypeScript together.


This workshop is a hands-on workshop.

Instead of the typical workshop flow, you will work through the exercises before I'll teach you the theory and background. This way, you will learn the most important concepts of Nuxt.js by doing and not by listening or copying lines of code from the slides.

After each exercise, we will go through the solution and theory together, reinforcing what you have learned.
