Browser check if IE or Edge code should work otherwise not, how to do it?

Question

JavaScript

Browser check if IE or Edge code should work otherwise not. But something is written wrong apparently.

function get_name_browser(){
var ua = navigator.userAgent;
if (ua.search(/YaBrowser/) > 0) return 'Яндекс Браузер';
if (ua.search(/rv:11.0/) > 0) return 'Internet Explorer 11';
if (ua.search(/MSIE/) > 0) return 'Internet Explorer';
if (ua.search(/Edge/) > 0) return 'Edge';
if (ua.search(/Chrome/) > 0) return 'Google Chrome';
if (ua.search(/Firefox/) > 0) return 'Firefox';
if (ua.search(/Opera/) > 0) return 'Opera';
if (ua.search(/Safari/) > 0) return 'Safari';
return 'Не определен';
}

var browser = get_name_browser();
if (browser == 'Edge'||'Internet Explorer') {
alert('Код сработал.');
} else {
alert('Код НЕ сработал.');
}

Answer 1

if (browser == 'Edge' || browser == 'Internet Explorer') {

or

if (['Edge' , 'Internet Explorer'].includes(browser)) {
