BuckleScript

Write safer and simpler code in OCaml & Reason, compile to JavaScript.

let result = Js.(
  [|1, 2, 3, 4|]
  |> Array.filter(x => x > 2)
  |> Array.mapi((x, i) => x + i)
  |> Array.reduce((x, y) => x + y, 0)
)

let result = Js.(
  [|1; 2; 3; 4|]
  |> Array.filter (fun x -> x > 2)
  |> Array.mapi (fun x i -> x + i)
  |> Array.reduce (fun x y -> x + y) 0
)
