detectBrowser.js

// You need to detect what browser is being used. Create a function that takes a string (browser identifier) and returns the browser name.

// Examples:
// detectBrowser("Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.87 Safari/537.36") ➞ "Google Chrome"
// detectBrowser("Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0") ➞ "Mozilla Firefox"
// detectBrowser("Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; .NET4.0C; .NET4.0E; .NET CLR 2.0.50727;
// .NET CLR 3.0.30729; .NET CLR 3.5.30729; rv:11.0) like Gecko") ➞ "Internet Explorer"

function detectBrowser(userAgent) {
  if (userAgent.includes("Chrome")) {
    return "Google Chrome";
  } else if (userAgent.includes("Firefox")) {
