TypeScript

About

TypeScript is a statically typed programming language developed by Microsoft as a superset of JavaScript. It adds optional static typing and other features to improve the development experience for large-scale applications. TypeScript is designed to work seamlessly with existing JavaScript code, allowing developers to leverage their JavaScript knowledge while benefiting from additional features like type annotations, interfaces, and generics. This compatibility means that any valid JavaScript file can be renamed to a TypeScript file and compiled without modifications. TypeScript's primary goal is to enhance maintainability and scalability by catching type-related errors at compile-time rather than runtime. TypeScript supports both client-side and server-side development, compatible with environments like Node.js, Deno, and Bun. Its features include type inference, which automatically determines types without explicit annotations, and support for advanced types like tuples and union types. The TypeScript compiler, `tsc`, transpiles TypeScript code into JavaScript, ensuring it can run anywhere JavaScript is supported. The language is free and open-source, licensed under the Apache License 2.0. TypeScript's adoption has been significant, with widespread use in modern web development due to its ability to enhance code reliability and tooling support.
