How a lesson works

  1. Read, then run

    Most ideas come with a short program you can edit. Press Run and the output appears under it, produced by a real copy of the language running in your browser.

  2. Do the exercise

    Every lesson has starter code and a target output. The page compares your output with the target and shows the first line that differs.

  3. Take the quiz

    A handful of questions, each with a short explanation. Answer every question and the lesson gets a check mark wherever the course lists it. Your progress is saved in your browser.
