What you'll learn in this Go course

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 think it balances hand holding and letting you figure it out on your own nicely.

If you aren't comfortable with Go yet, you're gonna learn one way or another.

The pokedex project is quite fun and allows you to explore implementation of code without step-by-step instructions.

Caching part made me sweat. Big difference in learning Go concepts, networking versus applying them all at once in a project. But this is where real learning happens so glad I finished it.
