Re: how do i find the index of a specific array value?

[hdp]

For very large arrays where bailing out as soon as a match is found is a win:

my @a = ( 1 .. 1_000_000 ); # some large array

my $want = 5843;
my $index = 0;
++$index until $a[$index] == $want or $index > $#a;

[hdp]

The last line should be ++$index until $a[$index] == $want or $want > $#a, and thanks to stephen for pointing this out.
