Iterate over two arrays using jQuery.each()?

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.

Answer 2

@PPvG this is the code I though, I got two arrays that contains few words each, and using $.each() I wanted to append them in <p> tag arr1 and arr2. content of arr1 first arr2 secondo it's no matter sequence. – Sam 4 secs ago

You could .concat them for the iteration:

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