Where can I find exercises and project ideas to learn Crystal?
The first one makes sense, I’m not sure of a problem with the second, but I’m not completely sure what it’s supposed to do.
Rosetta Code tasks are a good way to learn|see how to use Crystal to do them.
Check them out to see basic usage and more intricate implementations using Crystal for the various tasks. They’re still quite a few with no Crystal examples you might also want to try.
I posted the ongoing thread of coded tasks I/others have done since 2019. Copy|paste them into a file and run them, and|or modify them to your hearts content.
