Apps checking the OS version string on Windows has never made sense to me. I don't know of an easy way for an app to even determine the name of the release put on the other hand getting the version number in computer-readable form is stupidly easy.

If somebody isn't running Javascript why does it matter what version they have? AFAIK almost everything new in over ten years has been new JS APIs.

@hanro50 I haven't seen a browser popup an error dialog for Javascript since IE 5. I hadn't heard of fetch before but can't it be tested for by something like if("fetch" in window){useFetch()} else{useXHR()} ?

Version number parsing is useless for most purposes as user agent strings aren't standardized and different users may have different features enabled or disabled depending on their installation. Nowadays (and for over 15 years) you've been able to test for specific features which is more reliable than parsing strings.

@LubosMudrak Google started that stupidity over ten years ago. If a webapp is new enough to parse version strings as two digits instead of one it's also new enough that the stupid rapid incrementing version numbers were around.
