Intl.DateTimeFormat.prototype.format

by 4 contributors:

The Intl.DateTimeFormat.prototype.format property returns a getter function that formats a date according to the locale and formatting options of this Intl.DateTimeFormat object.

Syntax

dateTimeFormat.format(date)

Parameters

date
The date to format.

Description

The function returned by the format getter formats a date into a string according to the locale and formatting options of this Intl.DateTimeFormat object.

Examples

Using format

Use the function returned by the format getter for formatting a single date, here for Serbia:

var options = { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric' };
var dateTimeFormat = new Intl.DateTimeFormat('sr-RS', options);
console.log(dateTimeFormat.format(new Date()));
// → "недеља, 7. април 2013."

Using format with map

Use the function returned by the format getter for formatting all dates in an array. Note that the function is bound to the Intl.DateTimeFormat from which it was obtained, so it can be passed directly to Array.prototype.map().

var a = [new Date(2012, 08), new Date(2012, 11), new Date(2012, 03)];
var options = { year: 'numeric', month: 'long' };
var dateTimeFormat = new Intl.DateTimeFormat('pt-BR', options);
var formatted = a.map(dateTimeFormat.format);
console.log(formatted.join('; '));
// → "setembro de 2012; dezembro de 2012; abril de 2012"
