What will you learn?
A REPL, or Read-Eval-Print Loop, is a simple interactive programming environment that takes user input, evaluates it, and returns the result to the user. In this guided project, you'll build a Pokedex-like REPL in Go that uses the PokeAPI to fetch data about Pokemon. It's a great way to put your Go knowledge to the test and learn valuable skills like HTTP networking and data serialization.

Short but impactful—taught me exactly what I needed.

Fantastic! The explanations were crisp and the demos were grounded in real engineering scenarios. What stood out to me was the clear discussion around testing strategies and how to evolve a codebase over time. The sample repository was well-structured and made it simple to jump between sections. I’d love to see a follow-up lesson that goes deeper into profiling and performance tuning.

I appreciated how the instructor broke down the core concepts into digestible steps. The examples were practical and mirrored what I encounter in my day-to-day work. In particular, the section on error handling and observability tied everything together. If I had a minor nitpick, it would be that the pacing sped up in the last module, but the accompanying notes and code samples made it easy to revisit and cement the ideas.
