Explanation

On call of greet first it will find the element from the DOM on which you want to scroll up.
Here I have the user `mainboard` as an ID. if any changes are there you can update your ID over here.
Now with the help of scrollBy function call on element I am passing a few arguments with it.
First is the direction with the value. As we want to move up I have a user `top` with 0 value,
Second, I have added `behavior` with a `smooth` value to make the scroll look animated while going up from bottom.
