The Odin Project's TypeScript course teaches TypeScript (a typed superset of JavaScript) through projects. You learn types, interfaces, generics, and how TypeScript prevents bugs. The course is part of The Odin Project's free curriculum. After finishing, you can write type-safe JavaScript and understand TypeScript's benefits. The main limitation: TypeScript is a layer on top of JavaScript. You need solid JavaScript knowledge first, and real mastery comes from using it in larger projects.
TypeScript is used by 38.9% of professional developers and is one of the fastest-growing languages (source: Stack Overflow Developer Survey 2024).
About This Course
