What We Learned

At this point, you’ve got a perfectly functioning, if simple, browser-based spaceship game. Along the way, you learned about the power of creating your own operators and how they can not only be used to create new observables, but pass around the root observable chain, allowing you to isolate changes. You also picked up some animation techniques that work in both the canvas world and the regular DOM. Speaking of canvas, you learned the basic APIs and can now start venturing into building all sorts of games.
