How to scroll to the top of the page using javascript

Question: How to scroll to the top of the page using javascript

Answer:

You can see a live demo of this concept on our website, as we have also integrated 'Back to Top Button' on our website. Also, we have published a separate article on "Back to a top button using jquery", you can read that article. But in this article, we are using JavaScript to create a 'Back to top of the page' animation with a smooth experience.

First: the simplest code of 'back to the top of the page'. But these codes don't provide smooth scrolling.

window.scrollTo(0, 0);

Second: This code is also simple but these codes provide smooth scrolling.

window.scroll({
 top: 0, 
 left: 0, 
 behavior: 'smooth' 
});
