this is the question 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.)
this is my answer: const body = document.getElementsByTagName('body');
this answer did not pass the quiz check

Since there is only one body tag in the HTML, it is similar to a single array value, and you can grab the element by using square brackets like you do to array. So you could access the body element by using this code :
const body = document.getElementsByTagName('body')[0];

Courses Plus Student 5,242 Pointsdo you mean that the "body" variable will contain empty elements + the HTML body element?

Courses Plus Student 5,242 Pointsthat may be a better way to select the body element, but is my answer is a mistake? will it not run properly?

13,732 PointsYour code wasn't a mistake, but the variable itself contains html elements not the body element that the question wanted.
