AI translates the explanation and quiz text while preserving code and answer scoring.

`queueMicrotask()` schedules a callback to run after the current synchronous script finishes and before the event loop yields to the next macrotask or rendering.

js
queueMicrotask(() => {
  console.log("Runs before next timer or UI repaint");
});
