Phew! That's a lot of information that we learned, but what's the use if we don't use what we now know?! It's time to start building some fun projects using Deno. However, since Deno has built in support for TypeScript, we are going to start using TypeScript in our projects. Because depending on the student that is taking the course, some may know TypeScript and some may not, we have 2 paths to pick from to accommodate everyone:

1. If you aren't too familiar with TypeScript, head on over to Bonus: Learn TypeScript to get familiar with the basics of this superset of JavaScript. Once you are done with that section, come back here and continue with the course!

2. If you have already worked with TypeScript and know it well, you can ignore the Bonus: Learn TypeScript section and head on over to our first project in the next lesson!
