<div dir="ltr">Hi, <br>
I've been using imperative languages for 20 years now :)<br>
<br>
I'm a beginner in haskell and I love the paradigm shift you feel
when you come from imperative programming. I found interesting
articles like :<br>
<a href="https://wiki.haskell.org/Haskell_IO_for_Imperative_Programmers" target="_blank" rel="noreferrer">https://wiki.haskell.org/Haskell_IO_for_Imperative_Programmers</a><br>
<br>
Do you have any other ressources like that ?<br>
I'm not looking for how to use haskell in imperative style (e.g.
with "do" notation, ...) no no ! I'm looking articles who
explain how NOT TO USE imperative style with haskell, and help
thinking the paradigm shift ...<br>
<br>
Thanks :)<br>
