javaScript Scroll Function
A nice feature that you can add to your HTML page using javaScript is a scroll to top button. This is particularly useful if you have a long page. window.scrollTo(x, y); allows us to achieve this it takes a xand y coordinate and scrolls to that location. window.scrollTo(0, 0); will scroll to the top left section of our screen.
