run_code
Loads code into the open in-browser playground (Jai, Quasi or BaerScript, whichever is on this page), runs it and returns its output. The editor contents are replaced. Returns stdout, stderr, the exit status and diagnostics; output is cut at 20 KB and the run is stopped after 30 seconds. Jai restarts its compiler session first, so it takes longer.
