+## Get Scroll Position
+
+Get the current distance scrolled by `window` or `HTMLElement` as an {x,y} object
+
+```js
+const getScrollPos = (scroller = window) => {
+  let x = (scroller.pageXOffset !== undefined) ? scroller.pageXOffset : scroller.scrollLeft;
+  let y = (scroller.pageYOffset !== undefined) ? scroller.pageYOffset : scroller.scrollTop;
+
+  return {x, y}
+}
+
+// getScrollPos() -> {x: number, y: number}
+```
 ### Greatest common divisor (GCD)
 
 Use recursion.
