Developers using Deku can choose to also use JSX if they want to. This is especially helpful for people who are moving from React to Deku.

Con Not a lot of learning resources
Since it's a rather new library and has a small community, there are not many examples where you can learn from out there. There are also few guides and the documentation is not amazing and has some parts that should be covered better.
