Tips & Tricks
- Play: Experimentation is a powerful learning tool. Don't be afraid to try stuff out, and run it to see what happens.
- Run the Test: It is valuable to see what the results are. All Koans are designed to produce something even before they are filled in.
- Debug: Set some break point and walk through the code. It's a great way to get details. ({"Ctrl+R, Ctrl+T"}) will run in debug mode.
- Do Them with a Friend: Learning is more fun and less frustrating when you have a friend with you.
- Retrospect after each Koan: True insight comes from reflecting on the answer, not just obtaining it. Answer 1 question from this list
