The principle of judgment:    JavaScript is the main language of front-end development, we can write JavaScript programs to determine the type and version of the browser. JavaScript can determine browser types in general there are two ways, one is based on a variety of browser-specific properties to distinguish, the other is by analyzing the browser's useragent properties to judge. In many cases, after the value is judged by the browser type, it is also necessary to judge the browser version to handle the compatibility issue, and to judge the browser version is generally only through the analysis of the browser useragent to know.     Browser type    ⑴ browser-specific properties  ⑵ according to useragent  browser version  ⑴ according to useragent    for mobile browser to judge     1.
