How to use callbacks on jQuery each function?
I am trying something like:
$.each(images, function(key, value) {
new_images+= '<li><a href="'+value+'"><img src="'+value+'" alt="'+[key]+'" /></a></li>';
}, function (){
$('#Gallery').remove();
$('body').append('<ul class="gallery">'+new_images+'</ul>');
});

each(); is a synchronous function. That means you don't need a callback function inside because any code you write after $.
each(), which is used to iterate, exclusively, over a jQuery object. The $. each() function can be used to iterate over any collection, whether it is an object or an array. In the case of an array, the callback is passed an array index and a corresponding array value each time.
each() function, jQuery's foreach equivalent. jQuery's foreach equivalent can be very useful for many situations. These examples will get you started and teach you how you can loop through arrays, objects and all kinds of HTML elements.
each() jQuery's each() function is used to loop through each element of the target jQuery object — an object that contains one or more DOM elements, and exposes all jQuery functions. It's very useful for multi-element DOM manipulation, as well as iterating over arbitrary arrays and object properties.
$.each(); is a synchronous function. That means you don't need a callback function inside because any code you write after $.each(); will run affter $.each(); ends.
