How to detect a mobile device in Javascript?

There are several ways to detect a mobile device in JavaScript. One common approach is to use the navigator.userAgent property, which is a string that represents the user agent of the browser. This property can be used to detect the presence of certain strings that are associated with mobile devices.

Here is an example of how to use the navigator.userAgent property to detect a mobile device:

function isMobileDevice() {
  return /(android|iphone|ipad|mobile)/i.test(navigator.userAgent);

This function uses a regular expression to test the navigator.userAgent string for the presence of the strings 'android', 'iphone', 'ipad', or 'mobile'. The i flag makes the regular expression case-insensitive.

You can then use this function to determine if the user is viewing the page on a mobile device:

if (isMobileDevice()) {
  // do something for mobile devices
} else {
  // do something for desktop devices

Keep in mind that this approach is not foolproof, as it relies on the user agent string, which can be spoofed or changed by the user. It is also limited to detecting certain types of mobile devices, and may not work for all devices.
