‘Iacta alea est’
I have never been quite as excited about a programming language as I am about Elm. It’s been only two weeks since I first set eyes on it, yet I am completely and utterly sold. The last time I had a comparable experience was when Ruby with Rails convinced me, by their elegance and fitness for purpose, that I should in fact learn to program and make a career out of it.
Of course then the landscape was PHP and Java, so Rails didn’t have to do much to offer a better alternative, but it did that and more. The world of web development today is more akin to a technological Cambrian explosion, with the paradox of choice precipitating a paralysis in the programmers’ psyche.
That’s not to say it will necessarily be easy to master. I’m going to have to recalibrate my thinking to really become effective. But at no point have I had the feeling that it won’t be worth it—quite the opposite—Elm promises to educate me, and to leave me better off.
It is, however, easy to start. Evan Czaplicki, the author of Elm, has done a fantastic job in lowering the barrier for entry, from running your first program in the online editor/compiler to hiding some of the more advanced concepts behind
StartApp, a module made specifically for beginners.
It’s impossible to do Elm justice in a few paragraphs. I hope to make up for the sparse technical detail in later posts, but I recommend in the first instance that you try it and experience it for yourself—but be careful, you might just end up in Elm’s thrall.
