In this chapter, we learned what jQuery is, and what its strengths and benefits are. We also learned how to combine the powerful features of jQuery with CoffeeScript to write complex web applications with much less effort and complexity. jQuery is a very large library and we have just scratched the surface of what it has to offer. I urge you to spend some more time learning the library itself, and to do so using CoffeeScript.
Next up, we'll start by having a look at how you would start interacting with sever-side code using CoffeeScript and Rails.
