TypeScript allows you to provide static type information for existing (untyped) code via external files, which have the file name extension .

What type system does TypeScript use?

TypeScript’s Structural Type System

TypeScript is structurally typed, unlike most C-like languages which have a nominative type system. In a structural type system, two types are deemed the same if they have the same structure. So the explicit decoration is not required.

Is TypeScript frontend or backend?

Is it worth to use TypeScript?

TypeScript is 100% worth it. It’s how JavaScript should have been by default. The combination of static type checking with intelligent code completion provides a significant boost in developer productivity. Not only can you work faster, but you can also catch a ton of errors before they arise.

What is a static type checker?

In Static Typing, type checking is performed during compile time. … It means that the type of a variable is known at compile time. For some languages, the programmer must specify what type each variable is (e.g C, C++, Java), other languages offer some form of type inference(e.g. Scala, Haskell).
