One effective approach is to leverage feature detection in order to determine if the necessary features are supported by the current browser. The library modernizr offers a robust set of feature detection tools that can be directly integrated or selectively incorporated into your codebase. This method stands out as it eliminates the need to constantly monitor and adapt to individual browser updates, while also sidestepping potential inaccuracies associated with browser identification methods that can be manipulated by users. Feature detection allows for real-time assessment of whether a particular capability is present within the hosting browser, such as the ability to accommodate smaller screen sizes.
An alternative (though less preferable) strategy involves identifying the type and version of the user's browser and notifying them if they are using an untested version. By examining the navigator.userAgent property, one can parse through the information contained in the browser's user-agent string to identify specific browsers and their versions. A resourceful collection of browser detection techniques can be found in this library.
For those working with jQuery, leveraging jQuery.browser and jQuery.browser.version provides access to pre-interpreted user-agent data, simplifying the process of extracting browser-related information.
