quiz

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 collection, not a single element.)

why the answer isnt const body = document.getElementsByTagName('body')

Hi Alanis,

Your answer is returning an entire collection and you just want to return an element. Add an index [0] at the end of your answer and then you will return only the body element.
