Notes: This REPL replays from scratch each time, so “session” variables exist because earlier cells run again. Prefer print(...) / console.log(...) for results. Avoid top-level return (it ends the whole replay).

Output

Output is derived from replay. Each replay runs in a fresh sandboxed iframe to avoid accumulating timers/intervals.
