Format date in ES6

Question

I am formatting a Date, with not momentjs or any other library, just pure JS. And I want to know if there is a way to simplify this with ES6

let currentDate = new Date(); 

const videosInformation = {
  time: currentDate.getHours() + ':' + currentDate.getMinutes(),
  date: (currentDate.getMonth() + 1) + '/' + currentDate.getDate() + '/' + currentDate.getFullYear(),
  gameId: Math.floor((Math.random() * 5000) + 1)
};

I saw that in the DOM you use something like renderSomething={`something: ${someObj}`}

so you don't have to do renderSomething={"something: " + {someObj}}

is there something I should use to do that kind of format?

There's nothing in ES2015 that added something like strftime no. There's an ECMAScript internationalisation spec ecma-402 which enables localised time:

let [date, time] = new Date().toLocaleString('en-US').split(', ');

const videosInformation = {
  time,
  date,
  gameId: Math.floor((Math.random() * 5000) + 1)
};

Which would give you US localized 8/4/2015 and 5:29:19 PM Or if you really want a 24 hour clock:

new Date().toLocaleString('en-US', {hour12: false})

Then you can do a substring on the time if you want to strip out the seconds.

You can read more about date and time at MDT docs.
