Q: What is TypeScript?

A: TypeScript is a superset of JavaScript that adds optional static types and other language features, then compiles to plain JavaScript that runs anywhere JavaScript does.

Q: How does TypeScript differ from JavaScript?

A: Unlike JavaScript, TypeScript lets developers declare types, catch errors at compile time, and use advanced features such as interfaces and generics, while still producing standard JavaScript code for execution.

Q: Who created TypeScript and why?

A: Anders Hejlsberg designed TypeScript at Microsoft to provide a typed layer on top of JavaScript, improving developer productivity and code reliability for large‑scale web applications.

Q: Is TypeScript open source?

A: Yes, it is released under the Apache Software License 2.0 and its source code is hosted publicly on GitHub.

Q: What are the main use cases for TypeScript?

A: It is used for front‑end web development, Node.js back‑ends, and any project where JavaScript is required but developers want stronger type safety and tooling support.
