Detecting the Safari browser: The user-agent of the Safari browser is “Safari”. This value is passed to indexOf() method to detect this value in the user-agent string. One additional check is required in the case of the Safari browser as the user-agent of the Chrome browser also includes the Safari browser’s user-agent. If both the user-agents of Chrome and Safari are in the user-agent, it means that the browser is Chrome, and hence the Safari browser value is discarded.
When considering using the user agent string to detect which browser is being used, your first step is to try to avoid it if possible. Start by trying to identify why you want to do it.
