what's the answer?

How would you select the body element using document.getElementsByTagName, and store it in the variable body?

(Hint: Don't forget that this method returns a zero-based collection, not a single element.)

const body = document.getElementsByTagName('html')[1];

There's only one HTML element, so there won't ever be an index [1] for it. Similarly, there's only one body element, and that's the one the instructions are asking you to look for (instead of html).

And since there's only one, the only possible index is [0].
