how to get html date value in custom format javascript code example

Example 1: format date js

const t = new Date();
const date = ('0' + t.getDate()).slice(-2);
const month = ('0' + (t.getMonth() + 1)).slice(-2);
const year = t.getFullYear();
const hours = ('0' + t.getHours()).slice(-2);
const minutes = ('0' + t.getMinutes()).slice(-2);
const seconds = ('0' + t.getSeconds()).slice(-2);
const time = `${date}/${month}/${year}, ${hours}:${minutes}:${seconds}`;

output: "27/04/2020, 12:03:03"

Example 2: javascript date format

const d = new Date('2010-08-05')
const ye = new Intl.DateTimeFormat('en', { year: 'numeric' }).format(d)
const mo = new Intl.DateTimeFormat('en', { month: 'short' }).format(d)
const da = new Intl.DateTimeFormat('en', { day: '2-digit' }).format(d)

console.log(`${da}-${mo}-${ye}`)
