EventLoopModell
The Event Loop Model is a fundamental concept in asynchronous programming, widely used in modern programming languages and frameworks to handle concurrent operations efficiently. At its core, the model relies on a single-threaded loop that continuously processes events or callbacks, allowing applications to remain responsive without blocking the main execution thread.
In this model, the event loop waits for events—such as user input, network requests, or timers—to occur.
Key components of the event loop include:
- **Event Queue**: Stores pending events awaiting processing.
- **Callback Queue**: Holds asynchronous callbacks ready to be executed.
- **Timer Queue**: Manages scheduled tasks (e.g., setTimeout or setInterval).
- **Idle/Poll Phase**: Checks for I/O events or callbacks to execute.
Languages like JavaScript (in Node.js and browsers) and frameworks such as libuv (used by Node.js) implement
The model is distinct from multithreading, as it avoids the complexity of thread management while still enabling
