:point_right: By itself, getElementsByTagName returns an element collection.

But the question is asking you to assign a single element to the variable body.

You can extract a single element from a collection by indexing it, and since in this case there will be only one element in the collection, we know the correct index must be 0:

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