The code snippet you provided checks if two conditions are met before playing an answer text using the playAnswerText function:

1. The tts prop is truthy (true) and tts_autoplay is also true.
2. write_ed value from buttonData should be a non-empty string, representing "write ed" functionality.

If both conditions are satisfied, it calls the playAnswerText method with the current answer text.

Here's a brief suggestion to improve readability and maintainability:

onMounted(() => {
  // Check if tts is enabled and auto-play is set to true,
  // also ensure write_ed has some content and no update_time exists.
  if (props.tts && props.tts_autoplay && buttonData.value.write_ed.trim() !== '') {
    playAnswerText(buttonData.value.answer_text);
  }
});

Changes made:

• Wrapped buttonData.value.write_ed trimming in parentheses: (buttonData.value.write_ed.trim() !== ''). Parentheses can make the intent clearer, especially when dealing with conditional logic expressions.

This change enhances readability while keeping the same logic.
