It's a reference sheet for a programming language. Like it's clearly designed to be read as you're writing code. I don't understand in which circumstance you'd optimize such a document for mobile use.
You have never read documentation on something you’re not currently writing code with _right_ _now_? Or looked at documentation for something you worked on in the day as you’re on your way home from work?
I opened it on mobile because I was interested in seeing how they differ, even though I’m not using either right now.
It seems more like you're saying "It's ok that your toaster doesn't cook pop-tarts, you shouldn't be having those anyway--the sugar's bad for you." Your way of doing things might not be everybody's.
Nothing has to cater to anything but I'm still allowed to be annoyed that I can't read it on mobile.
What can I say I am a reliable person trying to make sure less people get sucked into Julia without learning of it's downsides. To be fair, the same could be said to you ;).
