About this Episode

Today on Elixir Wizards we are joined by none other than José Valim, the inventor of Elixir! Coming from the Ruby on Rails world, José found his way to functional programming and we hear all about the evolution of his philosophy and thought process around the time of the creation of the language. He gives us some great insight into why functional programming is so appealing to him and the problems he wanted to solve by creating Elixir. We chat about other languages and his use of Erlang, Elixir's three biggest influences and some important characters in the story. José also shares a bit of personal, behind the scenes stuff about his schedule and how he tries to stay as productive as possible. We finish off the chat, talking about performance and the measures José has taken in this regard. For all this and more from a true Elixir wizard, be sure to tune in!
