I also forget to add the additional solutions from the Exercism exercises. Whoops... I'm also getting used to storing code in random places. Time to change that habit a little bit by storing them in my notebook, instead. Nothing wrong with that, yeah?!

The all-time favorite client-side networking tool for basic stuff.

It is seriously one of the best free and open-source tool out there with the plethora of protocols, leading implementation for various protocols such as HTTP3, and a lot of configurable options to fully control your request.
