Re: How do I find the index of a specific array value?

in reply to How do I find the index of a specific array value?

You should use first() from List::Util. List::Util is a core module, unlike List::MoreUtils and other modules mentioned above, so it is portable and can be used with no extra effort.

use List::Utils qw(first);

my @array = qw( Apples Oranges Brains Toes Kiwi);
my $search = "Toes";

my $index = first {$_ eq $search} @array;

print "index of $search = $index\n";

    I meant 
    use List::Utils qw(first);
my @array = qw( Apples Oranges Brains Toes Kiwi);
my $search = "Toes";
my $index = first {$array[$_] eq $search} 0..$#array;
print "index of $search = $index\n";
