The `DOMContentLoaded` event is a DOMContentLoaded event that fires when the HTML document has been completely parsed and the DOM (Document Object Model) is ready. It signals that the browser has finished reading the HTML file and is ready to start building the DOM tree. Using it prevents errors when your JavaScript tries to access `document` before it's available.
