Detecting whether browser is 32 or 64 bit with Javascript

Question

How can I use Javascript to detect whether the user's browser is 32 or 64 bit? I read this article but it only says how to detect the version of a Windows OS, not the browser.

It's not. That article discusses how to detect the version of a Windows OS, not the browser. — Brinley, May 24 '18 at 18:08

You can't do this with client running JavaScript. The best you could do is, as you've said, look at the user-agent string and see what the OS is using, but even that isn't reliable as user-agent strings can easily be changed.

You would need code running at the OS level to get this data.

OP wants to know about the browser, not the OS, which these days, can be assumed to be 64bit... – dandavis May 24 '18 at 18:15
