I do not recommend Pluto for learning Julia, as its disallows variable reassignment between cells while not being able to keep track of changes in mutable structs (including vectors). I recommend using a Jupyter Notebook. I recently had difficulties putting Julia to work in a Jupyter Notebook, so I understand the allure of using Pluto (which is fully written in Julia), but I was able to put it to work in my Arch Linux machine and wrote a step-by-step guide on how to make it work: Jupyter and Jupytext through IJulia.jl (Jupytext does not really work) - #4 by Henrique_Becker
