This seem to be a discussion of different proposals for adding a "pipeline" operator to JavaScript. A pipeline passes an argument to a function, so foo |> bar is the same as bar(foo) Better overview here: https://gist.github.com/tabatkins/1261b108b9e6cdab5ad5df4b8021bcb5 https://gist.github.com/tabatkins/1261b108b9e6cdab5ad5df4b80... The main difference between the proposals seem to be if you should write (F# style): foo |> bar or (Hack style): foo |> bar(#) F# style is more elegant if the function takes a single argument, but Hack style adapt better when a function takes multiple arguments.
