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 Typescript that uses the PokeAPI to fetch data about Pokemon. It's a great way to put your Typescript 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 TypeScript.
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 TypeScript.
3
Pokedex
Bring your REPL and cache together to complete your fully functional Pokedex CLI.
