how to create a list of span for a given array

Question

Let\'s say I have an object which looks like that:

var users = [\'user1\', \'user2\'];

For this object I would like to create a list of span li

You also can use the Array.map method:

['user1', 'user2'].map(
    function(a){
        $('').html(a).appendTo($('body')); return a;
    }
);

Or even shorter:

$(['user1','user2'].map(function(a){return ''+a+''}).join(''))
 .appendTo('body');

Or even Array.filter ;)

['user1', 'user2'].filter(
    function(a){
        $('').html(a).appendTo($('body')); return true;
    }
);

Or jQuery.each on a jQuery object derived from the Array

$(['user1', 'user2']).each(
    function(i,a){
        $('').html(a).appendTo($('body')); return true;
    }
);
