Hands up if you've never actually seen FP out in the wild doing something. Not saying it's not out there or useful - just saying that after 20 years I'm yet to

Hands up if you've never actually seen FP out in the wild doing something. Not saying it's not out there or useful - just saying that after 20 years I'm yet to come across it once.

Ever use Facebook? WhatsApp? Discord? Telephones? Docker? Amazon EC2? Bought something in a Walmart store or on their websites? etc. etc. Some of their core, critical parts are written in functional programming languages. Just because you don't see FP out in the wild being conspicuous, doesn't mean it's not there ;-)

  Which parts in particular? Genuinely curious.

Well... chances are you've made thousands of phone calls through switches running Erlang. You may have used Emacs, Discord, Facebook, Pinterest, Spotify, Font Awesome, xmonad or visited web sites running Elm or an Elixir backend... or even driven a Volvo. Here's a list of companies using Haskell, with similar links to other functional languages: https://github.com/erkmos/haskell-companies https://github.com/erkmos/haskell-companies. It includes names like Facebook, Tesla, Klarna, Target and Kaspersky. Not to mention the FP paradigms used in Python, C++ and other languages. In fact, if you've never come across FP "in the wild doing something" then I suspect you're living very much off-grid.

  I meant in a professional capacity. But appreciate the use-case examples.
