Resources for Learning and Experimentation

Dear reader, I use this short chapter to list online resources that you may find interesting.

For a student navigating the steep learning curve of Haskell, visiting https://sabela.datahaskell.com offers immediate value by shifting the language from a rigid compilation loop into an interactive, reactive sandbox.

Sabela acts as a markdown-first reactive notebook where code cells dynamically “respond” to modifications, using a GHCi-backed evaluation model to recalculate dependent cells automatically.

Beyond acting as a playground, the Sabela community gallery hosted at this site functions as an indispensable pedagogical resource for real-world applications.
