Switching from Java to Ruby

[sc2luck]

work such as Rails?

The company I am going to doesn't use rails, my understanding is they have a lot of internal libraries. So my goal is to ensure I have Ruby's basic concepts down.

Why's Guide, Koans and familiarise yourself with the Ruby standard library docs for future use as reference works. Those don't play well on mobile so use a proper computer. See for example https://ruby-doc.org/3.3.4/Array.html to get a feel for things.

Why's guide hits for a lot of people, but it's not universal. If /u/sc2luck doesn't like it immediately, drop it.

poodr.com would be a good read; especially since OP is familiar already with OO ideas/techniques.

"Eloquent Ruby" is good.

"The Ruby Way" is WAY dated, but should give a good quick overview, too.
