使用Javascript进行Twitter风格的时间前格式化("2h")

function formatTwitterStyleTimeAgo(timeString) {
  const timeRegex = /(\d+)(\w+)/;
  const [, timeValue, timeUnit] = timeString.match(timeRegex);

  let timeInSeconds;
  switch (timeUnit) {
    case 's':
      timeInSeconds = timeValue;
      break;
    case 'm':
      timeInSeconds = timeValue * 60;
      break;
    case 'h':
      timeInSeconds = timeValue * 60 * 60;
      break;
    case 'd':
      timeInSeconds = timeValue * 60 * 60 * 24;
      break;
    default:
      return 'Invalid time unit';
  }

  const currentTimeInSeconds = Math.floor(Date.now() / 1000);
  const timeDifference = currentTimeInSeconds - timeInSeconds;

  if (timeDifference < 60) {
    return '刚刚';
  } else if (timeDifference < 60 * 60) {
    const minutes = Math.floor(timeDifference / 60);
    return `${minutes}分钟前`;
  } else if (timeDifference < 60 * 60 * 24) {
    const hours = Math.floor(timeDifference / (60 * 60));
    return `${hours}小时前`;
  } else {
    const formattedDate = new Date(timeInSeconds * 1000).toLocaleString();
    return formattedDate;
  }
}

const formattedTimeAgo = formatTwitterStyleTimeAgo("2h");
console.log(formattedTimeAgo);
