Why Browser detection is unreliable in JavaScript #1
Mostly browser detection is done using UserAgent.

In the code, we check the userAgent property of the navigator object, which contains information about the user’s browser. It then checks for the presence of the strings ‘MSIE’ or ‘Trident’ in the userAgent property, which indicate that the user is using Internet Explorer.
I have added multiple if statements to check for the presence of various strings in the userAgent property, indicating the presence of different browsers. For each browser that is detected, a corresponding console.log message is displayed. If the browser is not any of the ones listed in the if statements, an console log message indicating that the user is using some other browser will be displayed.

However, you have to Keep in mind that browser detection is not always reliable, as users can change their userAgent settings or use a different browser that doesn’t have the same userAgent value. It’s generally better to use feature detection, where you check for the presence of specific features or capabilities, rather than trying to determine the exact browser being used.
