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

What is the answer to the quiz question about using document.ElementsByTagName to fill the body variable?

Why is this incorrect?

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.)

const body = document.getElementsByTagName('body')

Thanks.

If you're trying to reference the first body tag, you would need to select the first item of the HTML collection. document.getElementsByTagName('body') returns a collection.

In order to select the first body tag:

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