Build Mini Apps

The best way to learn to code is to build toward a goal. { Coding for Kids } is designed to get you there. This site hosts all the code for easy reference. To understand and learn about the code, you can purchase a copy of the book here.

The goal of the mini apps

Our goal is to create over a dozen apps that let you explore the basics of JavaScript. Each app is unique and focuses on using specific coding concepts.

What's on this site?

The main site contains tutorials for many aspects of JavaScript. It's a detailed reference guide with examples to look at.

The code for The Mini Apps is also here. If you're stuck getting your code to work, you can check the code here to see what's up.
