The Navigator Object
Find out what is the Navigator object and how to use it
The window.navigator property exposed by browsers points to a Navigator object which is a container object that makes a lot of Web Platform APIs available to us.
The standard and widely implemented properties include:
cookieEnabledtrue if cookies are enabledgeolocationpoints to theGeolocationobject used by the Geolocation APIlanguagereturns a string representing the language currently active in the browseronLinereturns true if the browser is online (the browsers interpret this in different ways, be aware)serviceWorkertheServiceWorkerContainerobject assigned to the document (see Service Workers)userAgentthe name of the User Agent identifier of the browser
The standard methods include:
registerProtocolHandler()a way to let websites register as handlers for protocols.
There are many more methods and properties which are provided by APIs that are either experimental or implemented as drafts and not yet finalized, or just available on a tiny fraction of browsers, so I haven’t included them here but you can explore them all on MDN.
