Node.js based on event-driven architecture so every single operation and call in a script execute in asynchronous manner. This enables Node js to run on a single thread unlike other web technologies. It makes Node.js light-in-weight and It’s a main reason which makes Node Js as a most popular once.
Traditional SQL databases are based on relational model which uses tables. But Node.js applications use object databases like MongoDB. It uses document-based model that uses objects resembling JSON instead of tables
Applications build by other languages are less adaptive when additional scripts added for new requirements. Developers need to make changes deep inside the code. But Node.Js has a bunch of small applications instead of a single and large application. This features allow developers to add a new functionality with much ease, fast and no need to make changes deep inside the code.
Due to its simplicity lot of developers using Node.Js and it outshines other web applications. Almost all web servers and cloud-based hosting providers like Amazon , Google, Microsoft Azure and others support hosting of Node.js web applications In recent years lot of corporates giants use Node.Js. A global networking site LinkedIn moved from Ruby to Node to handle their mobile traffic. It reduced the number of servers 30 to 3, i.e. nearly 90% reduction in server usage and this system was upto 20 times faster. All these figures clearly indicates , Node. JS perform much faster than other technologies
