Comment trouver les détails du système d'exploitation à l'aide de JavaScript ?
JavaScript fournit diverses méthodes pour accéder aux informations sur le système d'exploitation de l'utilisateur. Voici un script complet qui vous permet d'obtenir des informations détaillées sur le nom et la version du système d'exploitation :
