Why the Creator of Ruby on Rails Prefers Dynamic Typing
"I write all novel client-side code as JavaScript instead of TypeScript, and it's a delight," says the creator of Ruby on Rails. Posting on Twitter, David Heinemeier Hansson opined that TypeScript "sucked out much of the joy I had writing JavaScript. I'm forever grateful that Yukihiro 'Matz' Matsumoto didn't succumb to the pressure of adding similar type hints to Ruby." When it comes to static vs dynamic typing, "I've heard a million arguments from both sides throughout my entire career," Hansson wrote on his blog today, "but seen very few of them ever convinced anyone of anything." But wait - he thinks we can all get along:Personally, I'm unashamedly a dynamic typing kind of guy. That's why I love Ruby so very much. It takes full advantage of dynamic typing to allow the poetic syntax that results in such beautiful code. To me, Ruby with explicit, static typing would be like a salad with a scoop of ice cream. They just don't go together. I'll also confess to having embraced the evangelical position for dynamic typing in the past. To the point of suffering from a One True Proposition affliction. Seeing the lack of enthusiasm for dynamic typing as a reflection of missing education, experience, or perhaps even competence. Oh what folly. Like trying to convince an introvert that they'd really like parties if they'd just loosen up a bit... These days, I've come to appreciate the magnificence of multiplicity. Programming would be an awful endeavor if we were all confined to the same paradigm. Human nature is much too varied to accept such constraint on its creativity...But it took a while for me to come to these conclusions. I'm a recovering solutionist. So when I see folks cross their heart in disbelief that anyone, anywhere might fancy JavaScript over TypeScript, I smile, and I remember the days when I'd recognize their zeal in the mirror. Hansson also sees the "magnificence of multiplicity" in positions about functional vs object-oriented programming. "Poles on both these axes have shown to deliver excellent software over the decades (and awful stuff too!)."
