Iterators

• Iterating over plain javascript array
• $.each accepts 2 parameters: the array to iterate over and an anonymous function
  • The anonymous function accepts 2 params also: the first one is the index and the other is the element variable that is yeilded:

var namesArray = ['bob', 'mary', 'alex'];
$.each(namesArray, function(index, name) {
  //code
})

• $().each is different because this iteration works only on jQuery objects!!

$('#div_name').each(function(index, element) {
  //code
});
