Firebase Cloud Messaging

Firebase Cloud Messaging (FCM) is a service that enables developers to send notifications and messages to users' devices, such as smartphones and tablets. It allows for real-time communication, like alerts, updates, or personalized content, even when the app isn't open. FCM handles message delivery reliably and efficiently, supporting multiple platforms (Android, iOS, web). It helps businesses keep users engaged, informed, or remind them of important events without needing to build complex messaging systems from scratch. Overall, FCM simplifies the process of reaching users directly on their devices with timely, targeted information.
