TypeScript for Professionals – 2023 Edition
I’ve been teaching TypeScript since 2012 (since launch). While teaching Juniors as well as Experts, I gathered a few tricks to make it an easy and smooth learning experience. I share those experiences with you. The objective is simple:
-
You can feel confident about what TypeScript is and offers
-
You become a competent TypeScript / JavaScript developer
A lot of effort has gone into this course to make sure you get all the knowledge you need, as quickly as possible.
Why TypeScript
I’ve been teaching and working with JavaScript for the past 10 years. TypeScript is hands down the best way to learn JavaScript. Give a beginner JavaScript developer a workflow with the TypeScript compiler and they can actually learn stuff themselves thanks to TypeScript’s excellent 1000+ compiler errors that prevent common mistakes.
Why this course
I’m a Microsoft MVP (Most Valuable Professional) for TypeScript thanks to my teaching contributions in the form of books, various videos and answers on StackOverflow.
This provides the best guidance possible for all the ways you can use TypeScript for your JavaScript projects to give you the most chances of success in your professional career. This course is based on my experience in that area and curated based on key workshop insights.
