An example of the difference between $. Each and $of. Each

The difference between $.each() and $().each,$.each is a generic iteration function that can be used to approximately iterate over objects and arrays, and $().each is dedicated to iterating and executing jquery object functions. While this function can be used to iterate over any object, the callback of this function contains two parameters: the first is the key (object) or index (array), and the second is the value.
