Define "other functional languages". Clojure(script) doesn't have fold, but reduce. F# has fold and foldBack.
What other languages do is, however, besides the point. The question is, what is more readable? It's easier to confuse foldl with foldr than it is to confuse fold(Left) with foldRight. This goes for both new and existing Elm developers. mandag 24. oktober 2016 13.12.53 UTC+2 skrev Rupert Smith følgende: > > On Thursday, October 20, 2016 at 3:12:57 PM UTC+1, Robin Heggelund Hansen > wrote: >> >> In Elm 0.18, primes are being removed as valid characters in a >> variable/function name.
