The Mechanics of Node.js
The power of Node.js is in its use of events. It operates by defining handlers for specific events and then waiting for those events to happen. At its core, it’s an event-driven non-blocking I/O model where it can perform other tasks instead of waiting for a response from the server (non-blocking). This behavior allows Node.js to handle multiple operations simultaneously, contributing to its fame as a highly scalable tool.
- Node.js also integrates libuv to manage asynchronous operations. Libuv communicates with the operating system, which in turn, triggers physical I/O operations.

The Main Challenges of Node.js
However, every rose has its thorns. The hallmark efficiency of Node.js is often negated by its single-threaded nature. This means that Node.js is unable to process other requests while one request is being processed, leading to potential inefficiencies in web application management. This weakness is further compounded by Node’s vulnerability to callback hell. This occurs when multiple nested callbacks are used, leading to a decrease in code readability and a consequent increase in debugging difficulty. Node’s solution to this problem is the concept of “Promises”, which often seem complex and unintuitive to developers, presenting a learning barrier.
