You are free to structure it differently:

    let x = anotherThing(
      somethingElse(
        something()
      )
    );

That's worse because now you have to find the innermost function and then walk back outwards. It gets especially ugly when the calls require other parameters

    let x = anotherThing(
      somethingElse(
        something(
         x, y, z
        ), 1, 2, 3
      ), "a", "b", "c"
    );

Or maybe this looks cleaner?

    let x = anotherThing(
      somethingElse(
        something(x, y, z),
        1, 2, 3
      ),
      "a", "b", "c"
    );

Neither is easy to follow.

I take you are no big fan of Lisp? /s

Well, actually I agree with you - sometimes. I have actually written helper functions to get similar pipeline processing capabilities in js.

    function pipe(...args) {
      return args.reduce((x, fn) => fn(x), null);
    }

    pipe(
      () => 2,
      (x) => 7*x,
      console.log
    )
