I have a Perl script that crunches a lot of data. There are a bunch of string variables that start small but grow really long due to the repeated use of the dot (concatentation) operator. Will growing the string in this manner result in repeated reallocations? If yes, is there a way to pre-allocate a string?
Alternate suggestion that will be much easier to cope with: push the strings onto an array and join it when you’re done.
