S a rethink of a #domain model and a major challenge is getting the architecture to a state where such #model and a major challenge is getting the architecture to a state where such doesn't have a ripple effect that makes every change hugely expensiveThe programmers who work on mainstream applications are rarely the target audience effect that makes every change hugely expensiveThe programmers who work on mainstream applications are rarely the target audience the static FP literature They are exactly the target audience or this book My goal is to make the most compelling case I can that static FP will give you new abilities especially new abilities or modeling a messy domain riddled with exceptions to the rules I aim to do that by teaching you idioms habits and design patterns that can make this style of programming an ordinary practice or you to perform–rather than a pile of ideas or you to connect. ,


K out click on SHOW AGAIN IT WORKS THIS RESTRICTION TO #show again it works This restriction to reliability matters because static FP languages are much obviously useful in cases where runtime errors can kill people Applications that work in messy domains Messy domains are ones like payroll systems that have to deal with decades of special cases negotiated by unions Or enterprise applications with a long history of salespeople making special deals to close big sales–deals that reuire special case code somewhere in the system Or generally any application in direct contact with people who can't be orced to behave in a consistent lawful way Applications that are continuously growing new I Love My Dad (Disney Princess) features Sometimes one of thoseeatures orce. Dynamically typed unctional languages like Clojure and Elixir #are now at the point where I eel comfortable basing a commercial application on them If you use #now at the point where I eel comfortable basing a commercial application on them If you use instead of Java or Elixir and Phoenix instead of Ruby on Rails you'll be ine Your app might still Camp Rex fail but it won't be because of the technology stackStatically typedunctional languages like Elm Purescript Haskell or Idris are definitely becoming popular but in my opinion are not Clearly Safe Bets For safe bets or applications By mainstream I mean Applications that reuire only ordinary reliability I sometimes see HTTP 500 errors on websites I shrug and try again Netflix via my Fire media player occasionally gets stuck loading a TV show I shrug bac.
