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

Posted by Max Toth

What about const body = document.getElementsByTagName('body'); is incorrect as a method to retrieve and store <body>?

This is in reference to quiz question 1 for Javascript and the DOM after the section on retrieving HTML elements by various methods

I have the same question. It seems to me that this would yield the same thing as: document.getElementsByTagName('body')[0];
since there is only one <body> element

so why aren't they both correct answers? (It would only accept the latter).

.getElementsByTagName() method returns a live HTMLCollection of elements. So if you want to get the <body> you must specify its position in the collection/array like: document.getElementsByTagName(‘body’)[0] or use another method, document.querySelector(‘body’)
