However, I’ve been reading reports that Julia is a pretty efficient programming language (here and here, for example). I need my code to run fast, I need it not to crash for memory-related issues… and R is the worst option for that. Don’t get me wrong, R has many useful packages, a great community and lots of online tutorials. It will always be my main programming language!

However, and as a shortcut to learning Python and Julia, I’ve written this cheatsheet with the help of ChatGPT (which makes a few mistakes but works pretty well for these things…). It combines the main coding tips and tricks for the three, R, Python and Julia (I might have missed something). I hope this can be useful!

I’m calling this “version 1” because I’m sure it has a few errors and imprecisions, and it might still be improved. However, here it is.
