Full Stack JavaScript Techdegree Graduate 22,885 PointsHow is this the wrong answer to the question?
How would you select the body element using document.getElementsByTagName, and store it in the variable body?
const body = document.getElementsByTagName('body');

When using getElementsByTagName we have to remember that it returns an HTML Collection rather than a single Element like getElementById, because of this we need to select the first item in the collection.
const body = document.getElementsByTagName('body')[0];
Your answer was correct except for missing the item selection.
Happy coding!

Full Stack JavaScript Techdegree Student 8,722 PointsShould the question not be 'How would you select the FIRST body element'? It's worded confusingly.

26,676 PointsAs explained in my original post, the getElementsByTagName method returns an HTML Collection. Specifying an index allows us to get the first element from the collection.
This isn't specific to the body element, it applies to any selector we use on this method.

26,676 PointsWhen using
getElementsByTagNameyou always have to select an item in the collection, an alternate way of accessing the body element is to use the below.const body = document.body;Hope that helps

7,303 PointsIn the example they don't select 1 item from the array, they use:
const myList = document.getElementsByTagName('li');
which I assume selects all <li> elements.
Wouldn't const body = document.getElementsByTagName('body'); just select all body elements (even though there's only 1)?

413 PointsI agree with Ben Herro: 'Should the question not be 'How would you select the FIRST body element'? It's worded confusingly.'
Although, unlike an <li> or <p>, I've never seen more than one <body> this question is not very good.?
