js method to determine whether the client is an iOS or Android mobile terminal_javascript skills

Judgement principle:

JavaScript is the main language for front-end development. We can judge the type and version of the browser by writing JavaScript programs. There are generally two methods for JavaScript to determine the browser type. One is based on the unique attributes of various browsers, and the other is determined by analyzing the userAgent attribute of the browser. In many cases, after the browser type is determined by value, the browser version needs to be determined to handle compatibility issues, and the browser version can generally only be known by analyzing the browser's userAgent.

⑴Browser-specific attributes
⑵According to userAgent
