NodeJS Architecture Explained

<h1>Origin Of NodeJS</h1> <p>Node.js is an open-source, cross-platform JavaScript runtime environment that allows developers to execute JavaScript code outside of a web browser. It was created in 2009 by Ryan Dahl and has since become one of the most popular JavaScript runtime environments, with a large and active community.</p> <p>Dahl noticed that the majority of web applications were heavily reliant on blocking I/O operations, which meant that the server had to wait for a response from an external resource before it could continue processing the next request. This led to poor performance and scalability, as the server could only handle a limited number of requests at a time.</p> <p>To address these limitations, Dahl created Node.js, which features an event-driven, non-blocking I/O architecture. This means that it uses an event loop to handle asynchronous I/O operations and can handle a large number of concurrent connections with high throughput and low latency.</p>
