Programming Languages

Learn a language properly — syntax, idioms and the runtime underneath.

Deep, project-driven courses on the languages developers actually ship with: C++, C#, F#, JavaScript, TypeScript, Lua, Python, Rust and Go. Every course pairs the syntax with the mental model, so you understand how the compiler or interpreter really treats your code. You finish able to read unfamiliar codebases, not just follow along with one.
