날짜변환하기

const date = new Date();

const year = date.getFullYear();
const month = ('0' + (date.getMonth() + 1)).slice(-2);
const day = ('0' + date.getDate()).slice(-2);
const hours = ('0' + date.getHours()).slice(-2);
const minutes = ('0' + date.getMinutes()).slice(-2);
const seconds = ('0' + date.getSeconds()).slice(-2);

const dateStr = year + '-' + month + '-' + day + ' ' + hours + ':' + minutes + ':' + seconds;
console.log(dateStr);
