Congratulations, you've successfully built a Web Component from scratch and evolved it into a LitElement!
Lit is super small (< 5kb minified + gzipped), super fast, and really fun to code with! You can make components to be consumed by other frameworks, or you can build full-fledged apps with it!
You now know what a Web Component is, how to build one, and how Lit makes it easier to build them!
Do you want to check your final code against ours? Compare it here.
