The getElementsByTagName() method returns a collection of an elements's child elements with the specified tag name, as a NodeList object. The NodeList object represents a collection of nodes. The nodes can be accessed by index numbers. The index starts at 0 (w3schools)

Correct code (Add index) 

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