Julia is a technical computing language, although it does have the capabilities of any general purpose language and you'd be hard-pressed to find tasks it's completely unsuitable for (although that does not mean it's the best or easiest choice for any of them). Instead of classes, some functional languages, such as Julia, have the concept of types. Yeah, that's the rank of Learn Julia The Hard Way amongst all Julia tutorials recommended by the programming community. In this way, it is very close to mathematics - so close, in fact, that it is based to a great extent on the concept of a lambda calculus, devised by Alonso Church, well before there were computers!
