- Q: What kind of programming language is TypeScript?
- A: TypeScript is a statically typed, object-oriented, and multi-paradigm programming language that is a super-set of JavaScript. It was developed and is maintained by Microsoft. TypeScript adds optional type annotations and class-based object-oriented programming to JavaScript and compiles to plain JavaScript, making it usable in any environment that JavaScript runs.

- TypeScript is a free and open source programming language developed and maintained by Microsoft. It is a strict syntactical superset of JavaScript and adds optional static typing to the language. It is designed for the development of large applications and transpiles to JavaScript. As it is a superset of JavaScript, existing JavaScript programs are also valid TypeScript programs. TypeScript may be used to develop JavaScript applications for both client-side and server-side execution (as with Node.js or Deno). Multiple options are available for transpilation. The default TypeScript Compiler can be used, or the Babel compiler can be invoked to convert TypeScript to JavaScript. TypeScript supports definition files that can contain type information of existing JavaScript libraries, much like C++ header files can describe the structure of existing object files. This enables other programs to use the values defined in the files as if they were statically typed TypeScript entities. There are third-party header files for popular libraries such as jQuery, MongoDB, and D3.js. TypeScript headers for the Node.js library modules are also available, allowing development of Node.js programs within TypeScript. The TypeScript compiler is itself written in TypeScript and compiled to JavaScript. It is licensed under the Apache License 2.0. Anders Hejlsberg, lead architect of C# and creator of Delphi and Turbo Pascal, has worked on the development of TypeScript.

- QUOTE: ... If you’re not yet familiar with TypeScript, it’s a language that builds on JavaScript and adds syntax for types. These types let you put your expectations and assumptions into your code, and those assumptions can then be checked by the TypeScript type-checker. This checking can help avoid typos, calling uninitialized values, mixing up arguments for functions, and more. Types go beyond checking though, and are used to give you a powerful editing experience for both TypeScript and JavaScript, enabling code completion, go-to-definition, renaming, and more. In fact, if you already use JavaScript in Visual Studio or VS Code, you’re already using TypeScript! ...
