java script print date in YYYY-MM-DD format

let date_ob = new Date();

// adjust 0 before single digit date
let date = ("0" + date_ob.getDate()).slice(-2);

// current month
let month = ("0" + (date_ob.getMonth() + 1)).slice(-2);

// current year
let year = date_ob.getFullYear();

// prints date in YYYY-MM-DD format
console.log(year + "-" + month + "-" + date);
