function getCommitTitle(commit) {
  const commitContent = commit.querySelector('.commit-row-title');
  const commitRowMessages = commitContent.querySelectorAll(
    '.commit-row-message'
  );
  const commitTitle = Array.from(commitRowMessages).reduce((title, message) => {
    title += message.innerText;
    return title;
  }, '');
  return formatCommitRawText(commitTitle);
}

需要更新下： ``` function getCommitTitle(commit) { const commitContent = commit.querySelector('.commit-row-title'); const commitRowMessages = commitContent.querySelectorAll( '.commit-row-message' ); const commitTitle = Array.from(commitRowMessages).reduce((title, message) => { title += message.innerText; return title; }, ''); return formatCommitRawText(commitTitle); } ```
