smoothScroll
Smoothly scrolls the element on which it's called into the visible area of the browser window.
Use .scrollIntoView method to scroll the element.
Pass { behavior: 'smooth' } to .scrollIntoView so it scrolls smoothly.
const smoothScroll = (element) =>
  document.querySelector(element).scrollIntoView({
    behavior: "smooth",
  });
smoothScroll("#fooBar"); // scrolls smoothly to the element with the id fooBar
smoothScroll(".fooBar"); // scrolls smoothly to the first element with a class of fooBar
