WHY are we using split() for this? Why are we using a method that

please ?
Thanks,
José.

I have a string which i know, it is a concatenation of fixed length of substring.
I would like to split it based on this known length and get as result
An array containing each substring.
Let say the known length is 2.
If the string is 'abcd', my array should be ('ab', 'dc')

my $string = hello there;
# add an extra '.' for every character you want
my @pairs = split(/(..)/, $string);
The only thing you want to be careful about is empty quotes/nothing (e.g. ''). For
