We check now if the runtime is less than the actual duration it should run, we gonna recall the animation method, until we reaches the target element with given duration. So next we gonna divide the total time our code has already run by the total desired duration to get a factor out of it. This function can be declared for smooth scroll in JS in two ways: window.scrollTo (x-coord, y-coord) window.scrollTo (options) The x-coord parameter defines the pixel value in the horizontal direction to which the page needs to be scrolled. So what we do is check the runtime by subtracting the current time stamp from the start timeStamp (which helps us to get the runtime). So our scrollToElem method takes 5 arguments namely startTime ( starting time stamp), currentTime ( current timeStamp), duration (to which our animation should run), scrollEndElemTop (target element top position), startScrollOffset(starting scroll position).
