JavaScript JavaScript and the DOM (Retiring) Getting a Handle on the DOM Selection Review

What did I type wrong to select the body by using document.getElementsByTagName?

My understand of the question is to tag the <body> from the html. So I wrote: const body = document.getElementsByTagName('body');

What did I do wrong?

Hi! See the hint? It reminds you that the getElementsByTagNamemethod returns a collection. What does that mean? It means that you can access the element through an index number. For example, how many body tags do you have on a page? One (normally). So, since the question asks you to select the body tag on the page using this method and knowing that this methods return a collection, you need to specify the index number of the selected element at the end of the method, like: const body = document.getElementsByTagName('body')[index of the element] Knowing that you have just one element, what is going to be your index number? Hope I gave you hints enough without giving you the answer! haha
