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.

Chapter List

1
REPL
A REPL (Read, Eval, Print Loop) is a simple interactive programming environment that takes user inputs, evaluates them, and returns the results. Learn how to implement one from scratch in Go.
2
Cache
When making network requests, one of the most common performance optimizations is to cache the results. Implement an in-memory cache for the PokeAPI in Go.
3
Pokedex
Bring your REPL and cache together to complete your fully functional Pokedex CLI.

I love how this course doesn't bother to hold your hand and simply tasks you and asks you to rely on what you've learned and look at documentation to pull the pieces together to be successful.

good guided project. Be aware that the individual steps take a bit longer than a classical lesson.
