How do you set a strftime with javascript?

Question

I need to custom format dates. In ruby, I would use strftime, or string formatted time, to accomplish this.

now = Time.new now.strftime '%a, %d of %b' #=> "Sat, 27 of Jun" 

Does javascript use strftime or some equivalent? How can I get a similar effect in javascript?

UPDATE

Arguments of toLocaleString method can also configure the format of the dates. This is supported in modern browser versions, you can see more information here.

let date = new Date(Date.UTC(2015, 5, 27, 12, 0, 0))  , options = {weekday: 'short', month: 'short', day: 'numeric' };  console.log(date.toLocaleString('es-ES', options)); //sáb. 27 de jun.

In JavaScript there are methods to create dates, but no native code to format. You can read about Date(). But there are libraries that do. Particularly for me the best library to use it deeply is MomentJS. So you can do something like as: moment().format('dd, d of MMMM')

However, if you do not want to use a library you have access to the following native Date properties:

var now = new Date();    document.write(now.toUTCString() + "<br>")  document.write(now.toTimeString() + "<br>")
