Title: Why is functional programming the new thing suddenly? Why are industries also vouching for it and slowly shifting from pure imperative code to as much functional as possible.<p>And I am not talking about functional languages like Haskell, OcaML, etc. It is the style of avoiding state wherever possible.<p>I get it that academia has been programming functionally for quite a long time. Academia do many things that seem weird at the moment but later may become fruitful in practical settings.
