You will learn how to write non-blocking code by breaking long-running for loops across multiple event loop ticks using setImmediate() recursively.
Most Node.js courses cover the event-driven architecture superficially. They explain that Node is asynchronous but fail to show you how the actually manages I/O. An intermediate-to-advanced guide flips the script. node.js beyond the basics pdf
In a basic setup, Service A calls Service B directly via HTTP. This creates tight coupling. Advanced architecture uses message brokers (like , Redis , or Kafka ). You will learn how to write non-blocking code
app.get('/users', (req, res) => res.json([ name: 'John', age: 30 , name: 'Jane', age: 25 ]); ); An intermediate-to-advanced guide flips the script
To go beyond the basics, you must understand the library and the specific phases of the Event Loop. A standard PDF guide on advanced Node.js will inevitably cover the Timers, Pending Callbacks, Idle/Prepare, Poll, Check, and Close Callbacks phases.
