Question

How can I iterate two arrays through a single call to jQuery .each()?

Something like this clearly won’t work:

$.each(arr1, arr2, function(i,v){
  //do something...
});

So how can this be done?

Answer 1

An alternative to .concat would be double $.each:

$.each([arr1, arr2], function() {
    $.each(this, function(i, v) {
        // do something
    });
});

This could turn out being faster if the arrays contain lots of items.
