Difference between $.each(selector) and $(selector).each()

$.each(selector) and $(selector).each()

In jQuery, there is an object iterator utility called $.each() as well as a jQuery collection iterator: .each() to run for each matched element.

We can return false to stop the loop early.



Basically, $.each() is essentially a drop-in replacement of a traditional for or for-in loop.

So, .each is an iterator which is used to iterate over only jQuery objects collection where as jQuery.each or $.each is a general function for iterating over JavaScript arrays and objects.

See jQuery reference for more details.

Example of JavaScript arrays and objects using $.each():

var myArr = [1,2,3];
jQuery.each( myArr, function(i, v) {
console.log('Element at index ' + i + ' is ' + v);

// Output
element at index 0 is 1
element at index 1 is 2
element at index 2 is 3
