Overview

Node.js has quickly become a popular choice for backend development due to its performant reputation. The traditional web server handles a web request by spawning a new thread and releases it only after the task is completed. This means a certain resource is being held on until the task is completed. Node.js is able to handle multiple web requests efficiently in a single-threaded environment. Instead of waiting for a certain resource to complete, Node.js is able to handle other requests while waiting for the previous resource to become available. This is referred to as non-blocking I/O (input/output) operations. Node.js is an efficient technology used for developing network applications that handle web requests at a lower cost.
