Kotlin syntax:
"1 2 3".split(' ').map { it.toInt() }
- yxhuvud 8y agoYour example doesn't do the same thing. The same as grandparent, in crystal: "1 2 3".split.map &.to_i.*(2)
- andyfleming 8y agoWhoops, you're right. "1 2 3".split(' ').map { it.toInt() * 2 }
- pmontra 8y agoI believe that Ruby also has that & shortcut (or similar) but it's totally unreadable. I never used it and I don't even want to check the exact syntax. Is it the only way it works in Crystal?
- yxhuvud 8y agoIt being readable is a matter of getting used to it. I find it more readable than the block version as there is less syntactic boilerplate. YMMV. Ruby has a similar version using colon instead of dot but that version isn't chainable and doesn't take arguments so it can't do the *2. And no, you can write out the full block just as you did in the Ruby version.
