onAllReady

onAllReady is a callback function or event handler that is typically invoked when all components or services within an application or system have finished initializing and are ready to accept requests or perform their intended functions. This concept is common in asynchronous programming and distributed systems where different parts of an application may start up at different times.

The primary purpose of onAllReady is to signal a state of operational readiness. This allows the main application logic to proceed only after all dependencies have been met and essential services are available. Without such a mechanism, an application might attempt to interact with a service that is not yet running, leading to errors or unexpected behavior.

In practice, onAllReady can be implemented in various ways depending on the programming language and framework. It might involve tracking the completion status of multiple asynchronous operations, such as network requests, database connections, or file loading. Once all these operations report success, the onAllReady handler is triggered. This ensures that the application is in a stable and functional state before it begins its core tasks or serves user requests. It promotes a more robust and reliable application by preventing premature execution of code that relies on uninitialized components.
