Firebase Functions

Firebase Functions are cloud-based pieces of code that run automatically in response to events, such as user actions or data changes, without needing your server to handle them. They enable developers to perform backend tasks—like sending notifications, processing payments, or updating databases—securely and efficiently. Because they run on Google's infrastructure, they scale automatically with demand, reducing the need for manual server management. Essentially, Firebase Functions let you extend your app's capabilities dynamically and securely, ensuring backend processes happen seamlessly and reliably behind the scenes.
