Answer 1

You can use moment.js npm i moment(您可以在npm i moment使用moment.js npm i moment)

import * as moment from 'moment'; // Get the date of birth as a moment const birthDateMoment: moment.Moment = moment(`${yourObject.birthday.day}/${yourObject.birthday.month}/${yourObject.birthday.year}, 'DD/MM/YYYY'); Option1: using duration : Get the duration time between now (moment()) and the birthDate(选项1：使用duration ：获取从现在（moment（））到birthDate之间的持续时间) const durationLife = moment.duration(moment().diff(birthDateMoment)) durationLife.years(); Option 2: Use diff(选项2：使用差异) moment().diff(birthDateMoment, 'years'); Option 3: time from(选项3：开始时间) birthDateMoment.from(moment());
