Today I started reading the Haskell chapter in the seven languages in seven weeks book. (https://pragprog.com/book/btlang/seven-languages-in-seven-weeks) In this blog series I will report my findings about the language and focus on the differences with languages like Java and C#.
One interesting thing that I noticed is that string concatenation happens using a double plus sign:
Prelude> "hello" ++ " world"
"hello world"
In order to concatenate characters together you will need to define a character array, this will result in a string.
