getScrollPosition	browser,intermediate

Returns the scroll position of the current page.

• Use Window.pageXOffset and Window.pageYOffset if they are defined, otherwise Element.scrollLeft and Element.scrollTop.
• Omit the single argument, el, to use a default value of window.

const getScrollPosition = (el = window) => ({
  x: el.pageXOffset !== undefined ? el.pageXOffset : el.scrollLeft,
  y: el.pageYOffset !== undefined ? el.pageYOffset : el.scrollTop
});

getScrollPosition(); // {x: 0, y: 200}
