Hands-on Project 5-1

For each of the 4 properties, specify whether the information returned seems accurate
~ I do not think the information seems accurate, at least some of it. For one thing the web browser name for all of them says Netscape. I used Firefox, Chrome and Edge for the three I tested. None of the ones I tested were Netscape Navigator.
Which of the properties are consistently different in each browser?
~ Minor differences in the User agent section for Chrome and Edge. Firefox has a more condensed answer for those two.
Which of the properties, if any, are the same for each browser?
~ The operating platform is exactly the same for each browser: Win32
Based on your results, explain any challenges you see in using the properties of the Navigator object to tell which browser an app is open in. Also explain whichi property or properties would deliver useful information.
~ I don't personally think that the information was all that good. It seemed to be showing all of the different browsers and not just the one that I opened the web page in, especially for Google Chrome and Microsoft Edge. Firefox's information seemed to be cleaner and apply more directly to just Firefox.
