Node.js

Node.js is an open-source JavaScript runtime environment that allows developers to create server-side applications and tools: 
 
 
  • What it does
    Node.js is used to run JavaScript applications outside of a browser, directly on a computer or server. It’s a popular tool for many types of projects. 
     
     
  • How it works
    Node.js is based on Google Chrome’s V8 JavaScript engine, which translates JavaScript code into machine code. Node.js is written in JavaScript and C/C++. 
     
     
  • Benefits
    Node.js is well-suited for data-intensive applications because it uses an asynchronous, event-driven model. This allows Node.js to handle thousands of concurrent connections with a single server. 
     
     
  • Use cases
    Node.js is a good choice for developing IoT systems, as it can process multiple concurrent requests and events from thousands of devices. It’s also a good choice for building scalable web applications. 
     
     
  • Limitations
    Node.js is not well-suited for CPU-intensive tasks, such as image and video processing or machine learning algorithms. In these cases, languages like Java, Python, or C++ might be better suited. 
     
     
Node.js was developed by Ryan Dahl in 2009.
