I just added some error handling for infinite loops and infinite recursion.

Before, if you wrote while (true) {} in the editor and pressed run, it would permanently lock up the UI and crash the browser tab. Now the logic test just interrupts the execution after 1000ms and fails your code for taking too long.

Likewise, if you wrote const r=()=>r();r(); and ran it, QuickJS would silently throw an uncaught error and the logic test would be stuck at “Waiting…” forever. Now it just instantly fails the code because it recurses too deeply and QuickJS can’t execute it.

I’m probably going to ship No Let soon, unless I have more puzzle ideas, find more bugs to patch, or think of more features to add.
