Tip: Lazy-load non-critical resources when a user interacts with UI requiring it. Your page may contain code or data for a component or resource that isnt immediately necessary. For example, UI a user doesnt see unless they click or scroll on parts of the page. This can apply to many kinds of first-party code you author, but this also applies to third-party widgets such as video players or chat widgets where you typically need to click a button to display the main interface.
