Navigator

Baseline Widely available *

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

* Some parts of this feature may have varying levels of support.

The Navigator interface represents the state and the identity of the user agent. It allows scripts to query it and to register themselves to carry on some activities.

A Navigator object can be retrieved using the read-only window.navigator property.
