Formatting a JavaScript date in modern browsers

In modern browsers, [Date.prototype.toLocaleDateString()](<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleDateString>) allows you to define the formatting of a Date in a convenient manner.

It requires the following format :

dateObj.toLocaleDateString([locales [, options]])

The locales parameter should be a string with a BCP 47 language tag, or an array of such strings.

The options parameter should be an object with some or all of the following properties:

• localeMatcher : possible values are "lookup" and "best fit"; the default is "best fit"
• timeZone : the only value implementations must recognize is "UTC"; the default is the runtime’s default time zone
• hour12 :possible values are true and false; the default is locale dependent
• formatMatcher : possible values are "basic" and "best fit"; the default is "best fit"
• weekday : possible values are "narrow", "short" & "long"
• era : possible values are "narrow", "short" & "long"
• year : possible values are "numeric" & "2-digit"
• month : possible values are "numeric", "2-digit", "narrow", "short" & "long"
• day : possible values are "numeric" & "2-digit"
• hour : possible values are "numeric" & "2-digit"
• minute : possible values are "numeric" & "2-digit"
• second : possible values are "numeric" & "2-digit"
• timeZoneName : possible values are "short" & "long"
