What is NodeJS?

Node.js is basically an open-source runtime environment for JavaScript code that runs outside a web browser. Ryan Dahl designed it in 2009 to allow developers to create JavaScript server-side programs. Node.js runs JavaScript on servers using the V8 JavaScript engine, originally built by Google for the Chrome browser.

It is ideal for building real-time applications like chat, online gaming platforms, and collaborative tools. Its event-driven nature and asynchronous capabilities enable seamless real-time communication. Node.js shines in the field of microservices architecture because it allows developers to design modular, scalable microservices that can communicate with one another easily.

Why NodeJS?

Node.js is known for its fast execution speed. Node.js translates JavaScript code into native machine code using Google’s V8 engine. It offers a unified development environment by enabling developers to use JavaScript on both the front and back. The seamless transition eliminates the need to switch languages for different application parts, reducing complexity and promoting better collaboration between frontend and backend teams.
