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 = _____________________

Hi, document.getElementsByTagName is a method that returns a collection of elements, it acts like an array. 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];

Ok thank you a lot. Frederic Ronaldi
