TypeScript

Xətaları erkən tutan tiplərlə JavaScript.

TypeScript is JavaScript plus a type system that catches bugs before your code runs, and it is one of the most popular languages in web development. This track takes you from your first type annotation to the patterns real-world apps use every day: object types, unions and narrowing, generics, utility and mapped types, satisfies, and validating API data at runtime.

You already know JavaScript, so every lesson goes straight to what TypeScript adds, and the quizzes make sure you truly understand what the compiler does.
