How can one solve this question? I used document.getElementsByTagName('body');

Is there some alternative way that I should write this?

You're almost right. Except, if you notice, the function is getElementsByTagName() not getElementByTagName(). Elements is plural. This is a good indication that it will select a collection of elements, not just a single element. In this case, you want to select the first body, which would be the first index in this collection:

const body = document.getElementsByTagName('body')[0];
