Node.js is well-suited for building microservices due to its non-blocking, event-driven architecture" highlights the key features of Node.js that make it a popular choice for building microservices

Node.js is designed to be non-blocking, meaning that it doesn't wait for I/O operations (such as file or network access) to complete before moving on to the next task. Instead, it uses an event-driven, asynchronous model.

In this example, the readFile function initiates a file read operation and registers a callback to handle the result. Meanwhile, the script continues to execute other tasks without waiting for the file read to complete.

Node.js uses an event-driven architecture where actions or occurrences (events) trigger the execution of associated functions (event handlers). This allows for efficient handling of many concurrent operations.

In this example, the myEmitter object is an event emitter. It listens for the ' myEvent' event and triggers the associated event handler when the event is emitted. This event-driven approach is beneficial for handling multiple, asynchronous operations concurrently.

Node.js is known for its ability to scale horizontally by handling a large number of concurrent connections with low resource consumption. This is achieved through its non-blocking, event-driven model and the efficient use of a single-threaded event loop.

Example: Consider a microservice handling multiple HTTP requests concurrently using a simple Node.js server.

In this example, the server can handle multiple concurrent requests without the need for threads or processes dedicated to each request. The asynchronous nature of Node.js allows it to efficiently manage a large number of connections.
