Advanced TypeScript Fundamentals
Instructor
Marius Schulz
Using TypeScript in your project has never been easier than it is today. The TypeScript team has continually added features to allow you to reap the benefits of static typing while reducing the overhead to get there.
This course will teach you these new language features TypeScript has to offer. You'll use optional chaining, handle undefined behavior with the unknown type and assertion functions, create private classes, handle tuple (and other data types) types, as well as learn about conditional types.
You'll also learn how to prevent type widening with TypeScript's new const assertions and efficiently type string literals through the use of template literals.
All of these skills will be brought together into examples that Marius will show you how to apply these new TypeScript features to real-world problems.

- Learnera year agoWhat did you like about this course?
I learnt TS by being assigned to a TS project mid way through, so I stumbled my way through it and just picked up what I needed for work. Always telling myself that I'll come back to learning it thoroughly, but never committing myself to it, this course taught me more in one hour compared to my months of stumbles. The most important part of this couse is being told to have a look at the actual type definitions of TS itself. You'd think after all these years of telling people to read the code that I would take my own advice :)
