Doping in Professional Bicycle Racing

Total time wasted here: 4.5h

Lesson learned

• Be careful with Date in JS. For this project, to set data-yvalue we need to use Date.toISOString(), so that new Date(string) (used in the test bundle) can parse it correctly. This burns me 2h.
• If in doubt, troubleshoot the test source code also.
• The test is usually right about whether there is anything wrong in our code. Test messages could be more informative, though.
