I'm a .Net developer and Angular developer who's been working with OO languages throughout my education and work history. Lately I've been thinking about spending some time with one of the functional programming languages, namely Haskell, to try and get a feel for what functional programming is all about.
My main reservations are on whether Haskell is a good language to start with and whether it is actually used anywhere in the industry. I guess the industry use question is more broad to target all functional languages. I have never personally met anyone who workingworked with functional programming language in their day today job. I'm basically trying to justify learning a functional programming language instead of another OO library or framework, relevant to my field.
