This presentation is more than five years old, and some of the details have changed. See https://julialang.org/learning/ for more up-to-date introductory material.
Can we add [2013] to the title?
Julia has changed substantially in the past 5 years…
Yes. Thanks!
Sure, but does Julia have an equivalent to ggplot2 and dplyr? These are my two most used packages for my daily work. If not, Julia is probably not worth it.
Plots.jl is a pretty darn good plotting library. If you prefer something more along the lines of grammar of graphics, checkout VegaLite.jl or Gadfly.jl. For dplyr, I just saw a presentation by Dr. David Anthoff on his QueryVerse.jl family of packages, and it's probably just what you're looking for.
That said, I do not recommend the linked article for learning Julia as it's highly out-of-date.
