TypeScript is a superset of JavaScript that adds optional static typing and other features to the language. TypeScript was created by Microsoft in 2012 and is designed to make it easier to write and maintain large-scale JavaScript applications.
TypeScript extends JavaScript by adding features such as classes, interfaces, enums, and generics, which allow developers to write more organized and maintainable code. It also provides optional static typing, which can help catch errors and improve code quality. TypeScript code is compiled into JavaScript code, which can then be executed by a web browser or server-side engine.
Overall, TypeScript is a powerful and flexible language that is designed to help developers write better code. By providing enhanced type checking, improved code organization, and better tooling support, TypeScript can help developers write more efficient, maintainable, and error-free code.
