Web application development in Node.js is not only a best option for developers but also for businesses. The five main reasons:
Thus, accessing file system, database and network is very fast in node. By using Node.js, developers can build fast and highly scalable network applications which are capable of handling bulk amount of simultaneous connections having high throughput.
It is Lightweight: Node.js operates on single thread, uses and event-driven and non-blocking I/O approach. Single thread uses to handle multiple concurrent requests. Node.js does not wait for any read and write operations, it always accepts request directly. This feature makes it lightweight and efficient to support hundreds of thousands of concurrent requests.
High Performance: Many big brands like PayPal, Walmart, LinkedIn moved to Node.js because of its high performance capability. In 2013, Walmart put all their mobile traffic via node.js on Black Friday, the busiest shopping time of the year. On that day, Walmart server did not go over 1% CPU utilization and yet they deploy with 200 million users online.
Easy to Modify and Maintain: Building applications on Node.js is easy because it has large and active community that contributes many useful modules that can be easily included and used.
