const y = h(g(f(x)))
const y = x |> f(%) |> g(%) |> h(%)
It get's better with const y =
g * k + j / w * d - 453368423
|> (x) => { 4566 * x + 46832 - x * x + 1 / x}(%)
|> (x) => { x / 4653 + 843 * x *x }(%)
|> (x) => { 486543 - x + x * x }(%)
The question is if you often do things like that, though ;)
