[removed] How to find out if the user browser is Chrome?

Question

I need some function returning a boolean value to check if the browser is Chrome.

How do I create such functionality?

Answer 1

To know the names of different desktop browsers (Firefox, IE, Opera, Edge, Chrome). Except Safari.

function getBrowserName() {
  var browserName = '';
  var userAgent = navigator.userAgent;
  (typeof InstallTrigger !== 'undefined') && (browserName = 'Firefox');
  ( /* @cc_on!@*/ false || !!document.documentMode) && (browserName = 'IE');
  (!!window.chrome && userAgent.match(/OPR/)) && (browserName = 'Opera');
  (!!window.chrome && userAgent.match(/Edge/)) && (browserName = 'Edge');
  (!!window.chrome && !userAgent.match(/(OPR|Edge)/)) && (browserName = 'Chrome');

  /**
   * Expected returns
   * Firefox, Opera, Edge, Chrome
   */
  return browserName;
}

Works in the following browser versions:

Opera - 58.0.3135.79
Firefox - 65.0.2 (64-bit)
IE - 11.413.15063 (JS Fiddle no longer supports IE just paste in Console)
Edge - 44.17763.1.0
Chrome - 72.0.3626.121 (Official Build) (64-bit)

The original code snippet no longer worked for Chrome and I forgot where I found it. It had safari before but I no longer have access to safari so I cannot verify anymore.

Only the Firefox and IE codes were part of the original snippet.

The checking for Opera, Edge, and Chrome is straight forward. They have differences in the userAgent. OPR only exists in Opera. Edge only exists in Edge. So to check for Chrome these string shouldn't be there.

As for the Firefox and IE, I cannot explain what they do.

I'll be adding this functionality to a package i'm writing
