I made a quiz about the JS Date parser is. It's very easy and you will score very high. jsdate.wtf

I knew this was a trick question after the earlier two about zero and one. But I never expected it to be this fucked up lol

This whole thing came about at work earlier this week when I realised “0” and 0 give different results. I tried “1”, okay, fine. Then “2” and that’s when I knew I had to make this quiz. Ended up reading the v8 code behind it to weed out other edge cases.

IIRC it's not even spec'd fully so you can get different results in different environments 🫠
