How can I format an ISO 8601 date to a more readable format, using Javascript? [duplicate]

Answer 1

The easiest would be to just work with the string

$(data).each(function(){

    var date = this.created_at.split('T') // split on the "T"   -> ["2015-11-09", "10:..."]
                              .shift()    // get the first part -> "2015-11-09"
                              .split('-') // split again on "-" -> ["2015", "11", "09"]
                              .reverse()  // reverse the array  -> ["09", "11", "2015"]
                              .join('/')  // join with "/"      -> "09/11/2015"

    var html = ' ' + date + ' ';
    $('#stream').append(html);
});

As it's a UTC date, just passing it do new Date() would add the difference of the timezone, and not always output the correct date.
If you need to validate the date, there are regexes for checking valid UTC dates.
