Javascript code-based browser rendering engine, platform, Windows OS, mobile devices, and gaming systems

This article mainly introduces information about browser rendering engines, platforms, Windows operating systems, mobile devices, and game systems that access web pages based on javascript code detection, if you need a friend, you can refer to the following nonsense and paste the js Code directly to everyone. The code is accompanied by comments. If you are interested, learn it together.

The above content is a summary of the javascript-based browser rendering engine, platform, Windows operating system, mobile devices, and game systems used to detect web pages. The following article describes how to check the client types of JavaScript learning notes (engines, browsers, platforms, operating systems, and mobile devices). Stay tuned .!
