js中怎么获取当前日期

let currentDate = new Date();
console.log(currentDate);

let now = new Date();

let year = now.getFullYear();    // 获取年份
let month = now.getMonth() + 1;  // 获取月份（注意：月份从0开始，所以需要加1）
let day = now.getDate();          // 获取日期

console.log(`Year: ${year}, Month: ${month}, Day: ${day}`);

let month = now.getMonth() + 1;

function formatDate(date) {
    let year = date.getFullYear();
    let month = ('0' + (date.getMonth() + 1)).slice(-2); // 补零操作
    let day = ('0' + date.getDate()).slice(-2);
    return `${year}-${month}-${day}`;
}

let formattedDate = formatDate(new Date());
console.log(formattedDate);
