Perl lightning talk: ”Don’t Fear map and grep”

This week’s Perl and Raku Conference 2022 in Houston was packed with great presentations, and I humbly added to them with a five-ish minute lightning talk on two of Perl’s more misunderstood functions: map and grep.

(Sorry about the ”um”s and ”ah”s…)

I’ve written much about list processing in Perl, and this talk was based on the following blog posts:

• Better Perl: Using map and grep
• Better Perl: Four list processing best practices with map, grep, and more
• Perl list processing is for hashes, too
• A list of Perl list processing modules

Overall I loved attending the conference, and it really invigorated my participation in the Perl community. Stay tuned as I resume regular posting!
