JavaScript Quest

JavaScript is the programming language that runs in every browser on Earth — it powers games, chat apps, animations and every button that does something. This quest takes you from your first console.log to writing functions that pass hidden tests, and finally to wiring up a real interactive page where your code reacts to clicks. Neby secretly tests your functions with surprise values, so only genuinely working code wins.
