navigatorID.platform

Returns a string representing the platform of the browser. The specification allows browsers to always return the empty string, so don't rely on this property to get a reliable answer.

Syntax

platform = navigator.platform 

Value

A DOMString. platform is a string that must be an empty string or a string representing the platform on which the browser is executing.

For example: "MacIntel", "Win32", "FreeBSD i386", "WebTV OS"

Example

console.log(navigator.platform);

Notes

On Firefox, unless your code is privileged (that is, running in chrome or at least has the UniversalBrowserRead privilege), it may get the value of the general.platform.override preference instead of the true platform.
