Alright, starting off with a warm welcome! Excited to dive into TypeScript, especially if it's going to make JavaScript development smoother.

Ah, so the core idea is compiling TypeScript down to JavaScript. That makes sense, since browsers and Node.js only run JS natively. Good to know we don't need to worry about a separate runtime for TS itself.
