如何查询moment js或date中昨天的数据？

var yesterday = moment().subtract(1, 'days').format('YYYY-MM-DD');
console.log(yesterday);

var today = new Date();
var yesterday = new Date(today);
yesterday.setDate(today.getDate() - 1);

var year = yesterday.getFullYear();
var month = ('0' + (yesterday.getMonth() + 1)).slice(-2);
var day = ('0' + yesterday.getDate()).slice(-2);

var yesterdayFormatted = year + '-' + month + '-' + day;
console.log(yesterdayFormatted);
