uniapp如何封装函数

const GetNowTime = time => {
var date = time,
year = date.getFullYear(),
month = date.getMonth() + 1,
day = date.getDate(),
hour = date.getHours() < 10 ? "0" + date.getHours() : date.getHours(),
minute = date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes(),
second = date.getSeconds() < 10 ? "0" + date.getSeconds() : date.getSeconds();
month >= 1 && month <= 9 ? (month = "0" + month) : "";
day >= 0 && day <= 9 ? (day = "0" + day) : "";
var timer = year + '-' + month + '-' + day + ' ' + hour + ':' + minute + ':' + second;
return timer;
}

const GetPhone = phone => {
let tel = phone.slice(0, 3) + '****' + phone.slice(7, 11);
return tel;
}
module.exports = {
GetNowTime,
GetPhone
}
