Can someone please tell me why my answer is wrong?

I have to select the <body> tag and make it a variable with the getElementsBytagName.

this is my code:

const body = document.getElementsByTagName[body];

The square brackets are for the index, calling the method still requires parentheses with the argument (given as a string) inside:

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

getElementsByTagName return a zero based collection so you need to type it like this:

document.getElementsByTagName("body")[0];
