> Finally, we have made no mention of one of Julia’s defining features, multiple dispatch.<p>That's pretty interesting. I suppose for a book like this (not having looked deep into it myself), you mostly need illustrative snippets of code that are largely self-contained, with the focus being on the algorithms, and so multiple dispatch doesn't really become necessary.<p>Also, it's really cool that every page is downloadable as a Jupyter notebook (+ a PDF + markdown)!
