Consider the example code here in Hack, const weather = `https://api.weather.gov/gridpoints/TOP/31,80/forecast` |> await fetch(%) |> await %.json() |> %.properties.periods[0] In F# it would be much more verbose, const weather = `https://api.weather.gov/gridpoints/TOP/31,80/forecast` |> fetch |> await |> json |> await |> x => x.properties.periods[0] // or |> { properties : { periods: [result] } } => result Hack will also requires less key strikes for calling functions that have multiple augments.
