> Trivia: F# is the language that made the pipeline operator (|>) popular.

I’m not a dabbler in exotic languages, so this definition of “popular” was puzzling. I’ve literally never seen that operator before. Maybe I need to get out more.



It exists in several similar languages such as elixir, and was even a proposal for ecmascript, but never really got traction.


I'm familiar with it via Julia, and I believe recent versions of R also have it.


It made it to Stage 2, which is some traction: https://github.com/tc39/proposal-pipeline-operator

It has been "stuck" at Stage 2 for a while, though.


Thanks for that link! Now I want pipe operators...


I've used it in Racket, which is not exactly "popular" but common in universities as a teaching language. I actually built a fairly popular Tor hidden search engine in Racket nearly a decade ago, but I quickly shut it down when I ran some stats on the most common queries.
