How to play

Every day at 00:00 UTC we publish one JavaScript snippet. Your job: predict exactly what it prints to the console.

You get 3 tries. After the first wrong try you learn the output's type; after the second, its shape. Quotes and extra spaces don't matter — 123 and '123' both count.

Multi-line outputs: enter one line per console.log call.

Solve it to keep your streak. Your stats live in your browser — we have no accounts and no server.

Yesterday's puzzle (with the full explanation of the trap) is always in the archive.
