In this chapter, we added the ability to use Julia scripts in our Jupyter Notebook. We added a Julia library that's not included in the standard Julia installation. We saw basic features of Julia in use, and also outlined some of the limitations that are encountered using Julia in Jupyter. We displayed graphics using some of the graphics packages available, including Gadfly, Winston, Vega, and PyPlot. Finally, we saw parallel processing in action, a small control flow example, and how to add unit testing to your Julia script.

In the next chapter, we will learn all about using JavaScript in a Jupyter Notebook.
