And also access them in the iex shell, even if offline, and the iex shell docs are exactly the same provided hex.pm.

I started using Elixir full time in 2018, coming from a JS and PHP background. I got a job working with Elixir and Phoenix full time. The first month was really hard, I felt like my head was going to explode from all the new concepts I had to take in at once.
One mistake that I kept making was forgetting to re-assign to variables, for example writing:
conn |> put_flash(:info, "You must log in to access the page")
# and more code after this
Which should have been
conn = conn |> put_flash(:info, "You must log in to access the page")
… because a variable is never modified in place, it needs to be reassigned explicitly. And there are no methods on data, it’s just data.
I love Elixir today, and after learning all the syntactic sugar and main concepts, it’s a joy to work with. Like the comments mention above, I think it’s really important working your way into it. It takes effort and some months to get good at it. I would recommend doing some projects in it, or completing some Advent of Code tasks. And if you can, get feed back and read other people’s code.
Some of my favourite features:
- Pattern matching
. Once you get that, you’ll miss it everywhere else. - Great tooling out of the box
- Immutability
- That everything is modules and functions. It’s a simple concept.

That’s basically what the blog post is. It’s a good overview of dialyzer and how it works. The thing that most stuck out to me was being able to use different symbols for specific types of primitive data types rather than overloading plus for multiple data types. Just helped me to see the purpose behind it.

On macOS there is even more awesome thing - Dash which is offline documentation browser with support for Erlang, Elixir, and Hex. So you can locally install documentation for packages that you use and easily search them all at once (so you do not need to remember whether given function is part of ecto or ecto_sql, you can search them both at the same time).

You also have it in Linux, I installed it once, several years ago, but didn’t like it.
Maybe I need to give it another try

I love dash so much!
There is also a vscode extension that allow to select any text and open its documentation in Dash with cmd - H shortcut

If you mean Zeal then I tried that in the past and this is nowhere near Dash (unfortunately).
