Accepted Answer

Use new Date() to generate a new Date object containing the current date and time.

var today = new Date();
var dd = String(today.getDate()).padStart(2, '0');
var mm = String(today.getMonth() + 1).padStart(2, '0'); //January is 0!
var yyyy = today.getFullYear();

today = mm + '/' + dd + '/' + yyyy;
document.write(today);

This will give you today's date in the format of mm/dd/yyyy.

Simply change today = mm +'/'+ dd +'/'+ yyyy; to whatever format you wish.

var utc = new Date().toJSON().slice(0,10).replace(/-/g,'/');
document.write(utc);

Use the replace option if you're going to reuse the utc variable, such as new Date(utc), as Firefox and Safari don't recognize a date with dashes.

UPDATED!, Scroll Down

If you want something simple pretty to the end-user ... Also, fixed a small suffix issue in the first version below. Now properly returns suffix.

var objToday = new Date(),
 weekday = new Array('Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'),
 dayOfWeek = weekday[objToday.getDay()],
 domEnder = function() { var a = objToday; if (/1/.test(parseInt((a + "").charAt(0)))) return "th"; a = parseInt((a + "").charAt(1)); return 1 == a ? "st" : 2 == a ? "nd" : 3 == a ? "rd" : "th" }(),
 dayOfMonth = today + ( objToday.getDate() < 10) ? '0' + objToday.getDate() + domEnder : objToday.getDate() + domEnder,
 months = new Array('January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'),
 curMonth = months[objToday.getMonth()],
 curYear = objToday.getFullYear(),
 curHour = objToday.getHours() > 12 ? objToday.getHours() - 12 : (objToday.getHours() < 10 ? "0" + objToday.getHours() : objToday.getHours()),
 curMinute = objToday.getMinutes() < 10 ? "0" + objToday.getMinutes() : objToday.getMinutes(),
 curSeconds = objToday.getSeconds() < 10 ? "0" + objToday.getSeconds() : objToday.getSeconds(),
 curMeridiem = objToday.getHours() > 12 ? "PM" : "AM";
var today = curHour + ":" + curMinute + "." + curSeconds + curMeridiem + " " + dayOfWeek + " " + dayOfMonth + " of " + curMonth + ", " + curYear;

document.getElementsByTagName('h1')[0].textContent = today;
<h1></h1>

UBBER UPDATE After much procrastination, I've finally GitHubbed and updated this with the final solution I've been using for myself. It's even had some last-minute edits to make it sweeter! If you're looking for the old jsFiddle, please see this.

This update comes in 2 flavors, still relatively small, though not as small as my above, original answer. If you want extremely small, go with that.
Also Note: This is still less bloated than moment.js. While moment.js is nice, imo, it has too many secular methods, which require learning moment as if it were a language. Mine here uses the same common format as PHP: date.

Flavor 1 new Date().format(String) My Personal Fav. I know the taboo but works great on the Date Object. Just be aware of any other mods you may have to the Date Object.

//  use as simple as
new Date().format('m-d-Y h:i:s');   //  07-06-2016 06:38:34

Flavor 2 dateFormat(Date, String) More traditional all-in-one method. Has all the ability of the previous, but is called via the method with Date param.

//  use as simple as
dateFormat(new Date(), 'm-d-Y h:i:s');  //  07-06-2016 06:38:34

BONUS Flavor (requires jQuery) $.date(Date, String) This contains much more than just a simple format option. It extends the base Date object and includes methods such as addDays. For more information, please see the Git.

In this mod, the format characters are inspired by PHP: date. For a complete list, please see my README

This mod also has a much longer list of pre-made formats. To use a premade format, simply enter its key name. dateFormat(new Date(), 'pretty-a');

As you may notice, you can use double \ to escape a character.

The shortest possible.

To get format like "2018-08-03":

let today = new Date().toISOString().slice(0, 10)

console.log(today)

To get format like "8/3/2018":

let today = new Date().toLocaleDateString()

console.log(today)

Also, you can pass locale as argument, for example toLocaleDateString("sr"), etc.

2018/08/05

If you just want a date without time info, use:

var today = new Date();
    today.setHours(0, 0, 0, 0);

document.write(today);

2016/07/08

Try this:

var currentDate = new Date()
var day = currentDate.getDate()
var month = currentDate.getMonth() + 1
var year = currentDate.getFullYear()
document.write("<b>" + day + "/" + month + "/" + year + "</b>")

The result will be like
