To get the focussed element in a webpage using JavaScript, you can use the activeElement property in the global document object.
For example, Consider you have a lot of anchor tags in your webpage and needed to find out which anchor tag has the current focus. The document.activeElement property will return a reference to the current focussed element (not limited to anchor tags).
// Get focussed element in a webpage ✨
const focussedElement = document.activeElement;
console.log(focussedElement);
See this example live in JSBin.
