What is TypeScript?

TypeScript is a statically typed language that compiles to plain JavaScript. It helps developers write more reliable and scalable code by providing type-checking and enhanced tooling support.


Key Points about TypeScript:

  • Static Typing: TypeScript introduces optional static typing, helping catch potential errors at compile time.

  • Object-Oriented Features: It offers features like classes, interfaces, and inheritance to structure your code better.

  • JavaScript Compatibility: TypeScript is compatible with existing JavaScript codebases, meaning you can incrementally adopt it in your projects.

  • Tooling Support: TypeScript integrates well with IDEs, offering advanced autocompletion, inline documentation, and error checking.
