Hi all.
I have read the explaination of the Map function and it is still a mystry to
myself on what it is for and when would you use it?
All explainations I have seen in books and blogs don't make it clear.
my @new = map {$_} @arr;
is the same as:
foreach (@arr) {
push $_, @new;
}
ITYM
foreach (@arr) {
push @new, $_;
}
Trying to use a scalar as the first argument to push will result in an
error message.
