js time to practice

编写代码，将当前日期按“2017-12-27 11:11 星期三”格式输出
    
var t1 = new Date();

console.log(t1.toLocaleString());
const WEEKMAP = {
  0:"星期天",
  1:"星期一",
  2:"星期二",
  3:"星期三",
  4:"星期四",
  5:"星期五",
  6:"星期六"
};

function showTime() {
    var t1 = new Date();
    var year = t1.getFullYear();
    var month = t1.getMonth() + 1;
    var day = t1.getDate();
    var hour = t1.getHours();
    var minute = t1.getMinutes() < 10?"15"+t1.getMinutes():t1.getMinutes();

    var week = WEEKMAP[t1.getDay()];

    var strTime = `
    ${year}-${month}-${day} ${hour}:${minute} ${week}`;
    console.log(strTime)
}

showTime();
