This code starts by getting the element with the id "license" and saves it to a variable called licenseElement. It then gets the element with the id "button" and saves it to a variable called buttonElement.

Next, it adds an event listener to the buttonElement which listens for a "click" event. When the button is clicked, it adds the class "hidden" to the licenseElement.

The "hidden" class presumably has a display:none property in the CSS file. By adding this class to the licenseElement, it achieves the desired effect of hiding the element.
