What is TypeScript used for?

TypeScript is an over-set to JavaScript adding static typing to the language, hence enhancing the reliability and readability of codes. It finds broad applications in the development of large-scale applications on both the frontend and backend by offering such features as type annotations and interfaces, which provide better tooling for capturing errors much earlier in the development flow. Particularly, TypeScript shines with frameworks like Angular, React, and Node.js, where it enables developers to create scalable and maintainable codebases with first-class tooling support. Structuring code and granting type safety, TypeScript makes it easier to handle complex projects and collaborate within larger teams.
