TypeScript 3.7.5

Are you using TypeScript, but feel like you’re not making the most out of it? Do you find some advanced TypeScript concepts confusing? Do you get lost looking at complex type errors?

If you answered “yes” to any of these questions, then this course is for you! It introduces you to the world of advanced TypeScript concepts including: compiler flags for catching more errors, generic types, and how to compose types with discriminated unions. 

After finishing this course, you’ll feel more confident in your TypeScript skills. You will be able to write types that detect whole classes of possible runtime errors at compile time. Typing even the most untypeable JavaScript code will be a no brainer for you, and you’ll be fluent in TypeScript error messages.

Advanced TypeScript Masterclass

This last chapter focuses on practical applications of TypeScript.

The first three lessons deal with the topic of debugging TypeScript compile errors. Error messages in TypeScript are infamous for their complexity. The lessons in this chapter aim to teach you how to approach them by providing some examples.

The second part of the chapter contains examples showing how TypeScript is used in some libraries. The advanced typing scenarios in this chapter are a perfect practice ground for the concepts taught throughout the course.
