Example to extract type from argument with generic types
// Given type definition below
interface IQueryType { params: any, result: any }

run: (params: T['params']) => T['result']

shiawuen / Samsung Browser
Created July 20, 2017 05:06 — forked from NielsLeenheer/Samsung Browser
Samsung Browser
Note: Some older devices such as the Galaxy S III did not get the Chromium based browser with
the update to Android 4.2 or later. When Samsung later introduced the Galaxy S3 Neo it did get
the new browser.
Note: With the Android 4.3 release and version 1.5 of the Chromium browser, Samsung did not
enable WebAudio API for the Note 3. All other devices did get the WebAudio API.
Note: Samsung did not update the browser version with the upgrade from Android 4.3 to 4.4,
but did add getUserMedia and WebRTC functionality.
