JS实现生成一个周对应日期数组

/* 获取日期和周 */
  getDateWeek() {/* 得到当前日期的时间戳 */
    const timestamp = Date.now()
    // const timestamp = new Date(2019, 7, 30, 0, 0, 0, 0).getTime()
    const dateWeek = Array.from(new Array(7)).map((_, i) => {
      /* 得到当前周每一天的时间戳 */
      const weekTimestamp = new Date(timestamp + i * 24 * 60 * 60 * 1000)

      const date = String(weekTimestamp.getMonth() + 1).padStart(2, '0') + '.' +
        String(new Date(weekTimestamp).getDate()).padStart(2, '0')

      /* 得到周几后转换 */
      let week = weekTimestamp.getDay()
      switch (week) {
        case 0:
          week = '周日'
          break
        case 1:
          week = '周一'
          break
        case 2:
          week = '周二'
          break
        case 3:
          week = '周三'
          break
        case 4:
          week = '周四'
          break
        case 5:
          week = '周五'
          break
        case 6:
          week = '周六'
          break
      }

      return {
        date,
        week 
      }
    })
　　console.log(dateWeek)
　　//得到如下结果
　　

  },
