The Event Loop

Understand the role of the Node.js event loop in managing asynchronous tasks efficiently on a single thread. Learn how the event queue and API pool work together to handle background processes without blocking, and discover the limitations of Node.js for compute-intensive tasks.

Concurrency

While we have praised Node.js for running applications on a single thread, there is more to it. When we ask the OS to read a file for us, we use the file system API. Node.js provides us with several APIs that allow us to make asynchronousprocesses that can run in the background without causing the main program to wait calls. For Node.js, these underlying APIs are written in C++ and threads are hidden from us. If you have ever worked with threads before, you will realize that things ...
