In Erlang and OTP in Action, Joe Armstrong is quoted as saying (and I&#x27;m paraphrasing here &#x27;cause I don&#x27;t have the book in front of me) - &quot;First, make it correct. Then, make it beautiful. Then, if you need to, make it performant. Because 9 times out of 10, making it beautiful also makes it performant enough.&quot;
