It's funny how the language you primarily work with changes your perspective.

JavaScript supports "object spreading", which lets you do this:

  let foo = { x: 1, y: 2 };
  ...
  let { x, y } = foo;
  console.log(x + y); // 3

A common pattern is to use this as a stand-in for named/unordered function arguments:

  function bar({ x, y }) {
    return x + y;
  }

  bar({ x: 3, y: 4 });

  // or...
  let foo = { x: 1, y: 2 };
  bar(foo);

Which is pretty much exactly the "epiphany" at the bottom (the interchangeability of these two). I don't mean to diminish the author's thought process; I just think it's fascinating how different programming languages (even ones so similar in syntax) dramatically shape the way one thinks about a given problem.
