I added a new chapter today: In-memory State!

I explain how to use Agents, ets, dets, or persistent_term to store state in your Elixir application. I also added Big-O complexities for ets and persistent_term where possible. Check it out!

Thanks, that’s neat.

Currently I am going through “Lists and Tuples”. I’m not sure if it’s good to have multiple lines in one livebook block and not be possible to evaluate each line on its own… If someone looks at that on a small device, he has to scroll down, up, down, up,… and associate each result to the correct line. Have you already put some thought into this? (Edit: I see now, that you put the number als label therefore. Maybe it’s better to put a short description there? As “get 2nd element”…)

Also, I would mention the Elixir version very soon. I know Elixir doesn’t change much these days, but someone with little experience with Elixir doesn’t know that. Personally, I wouldn’t use a JavaScript, Go or Rust guide if I didn’t know what version it was written for (maybe it’s out of date), so I would mention the version right in the beginning and also that the guide will be close to correct even if the reader’s version is not too far in the future. (Plus a link where to inform you if anything isn’t working anymore → Github?).

It’s from the pattern matching section, and it’s actually part of a note exactly about why it doesn’t work, and gives two options for actually determining if the map is empty.

I know what you mean, but it seems like even the Elixir docs use the term “operator”. Erlang also does.

They are technically functions / macros but they have the infix notation enabled for them.

You can just use them like this:
