javascript - Detect Safari browser

Question

How to detect Safari browser using JavaScript? I have tried code below and it detects not only Safari but also Chrome browser.

function IsSafari() {

  var is_safari = navigator.userAgent.toLowerCase().indexOf('safari/') > -1;
  return is_safari;

}

Note: always try to detect the specific behavior you're trying to fix, instead of targeting it with isSafari?

As a last resort, detect Safari with this regex:

var isSafari = /^((?!chrome|android).)*safari/i.test(navigator.userAgent);

It uses negative look-arounds and it excludes Chrome, Edge, and all Android browsers that include the Safari name in their user agent.
