The Page Lifecycle API allows you to access application lifecycle features that are common on mobile operating systems to the web. It provides lifecycle hooks that handle browser interventions without affecting the user experience. This is a way for browsers to freeze and discard background pages in order to conserve resources. It is based on a W3C Web specification that supports a browser's ability to manage the lifecycle of web pages. The World Wide Web Consortium develops interoperable technologies that includes specifications, guidelines, software, tools and more.
