There are several ways:
use List::MoreUtils qw/mesh/; print join ' ', mesh @ID, @name;
# you lose the order and every id must be unique my %h; @h{@ID} = @name ; print join ' ', %h;
or ...

    Once you have the list that you want to print; you don't need to use a join join, instead you can just print it with $, set appropriately. $, is also known as $OFS and $OUTPUT_FIELD_SEPARATOR; use perldoc perlvar. This can be much more efficient even with small lists.
    my @arr = ( 1, "Ali", 2, "Bobbi", 3, "Charli" ); local $, = " "; print @arr, $/;
    Be well,

    Updated: join usage

    Updated: efficiency comment deleted.

      Using $, is just another way. But internally $, use join and is __not__ faster or more efficient as the join statement.
        You are right; thanks for the correction.

        Be well
