Вначале была NCSA Mosaic, и Mosaic называлась сама собой NCSA_Mosaic/2.0 (Windows 3.1), и Mosaic показывал картинки вместе с текстом, и было много радости.

15 лет спустя ...

А затем Google создал Chrome, а Chrome использовал Webkit, и он был похож на Safari, и хотел, чтобы страницы создавались для Safari, и поэтому притворялся Safari. Таким образом, Chrome использовал WebKit и притворялся Safari, а WebKit притворялся KHTML, а KHTML притворялся Gecko, а все браузеры притворялись Mozilla, и Chrome называл себя Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.2.149.27 Safari/525.13, а строка пользовательского агента была полным беспорядком, и почти бесполезны, и все притворялись, что все остальные, и смятение изобиловало.

Прочитайте полную историю здесь ...

Получив строку User Agent, верните браузер, которому она соответствует.

Вы должны поддержать:

  • Хром / Хром *
  • опера
  • Fire Fox
  • IE
  • край
  • Сафари

Ваш код только должен удовлетворять всем этим тестам.

Почему нам не нужно обнаруживать Mozilla 1-4, как следует из названия?

Попробуйте онлайн! Объяснение: Opera может быть идентифицирована по (O)P(R/)платформе, а IE - по Tr(ident)движку. Другие браузеры включают свои полные имена в свои пользовательские агенты, но Edge ставит их в последнюю очередь, поэтому они должны обрабатываться отдельно от других. Редактировать: 1 байт, обнаружив Edge после Trident, и 1 байт, обнаружив Opera, используя только Pоба, благодаря @ThePirateBay.
