          **suggestion:** Make the video limit configurable instead of hardcoding

Consider making the limit parameter configurable or consistent with limits used elsewhere in the application. This would provide more flexibility and maintainability.

const DEFAULT_LIMIT = 6;

const fetchVideos = async (subtopic: string, limit: number = DEFAULT_LIMIT): Promise<Video[]> => {
  const response = await fetch(`/api/videos/?subtopic__name__iexact=${subtopic}&limit=${limit}`);
  const data = await response.json();
  return data.results;
};
