Difference between element.each and .each(element) in jquery

Question

What is the difference between

$(element).each(function(){
});

And

$.each("element",function(){
});

Answer 1

There is a difference. Per the docs:

The $.each() function is not the same as $(selector).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 a map (JavaScript object) or an array. In the case of an array, the callback is passed an array index and a corresponding array value each time. (The value can also be accessed through the this keyword, but Javascript will always wrap the this value as an Object even if it is a simple string or number value.) The method returns its first argument, the object that was iterated.
