BuckleScript
A faster, simpler and more robust take on JavaScript.
let result =
  [|1, 2, 3, 4|]
  -> Belt.Array.keep(x => x > 2)
  -> Belt.Array.mapWithIndex((x, i) => x + i)
  -> Belt.Array.reduce(0, (x, y) => x + y)
  -> Js.log;

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