Following are some of the important features that make Node.js the first choice of software architects.
Asynchronous and Event Driven
All APIs of Node.js library are asynchronous, that is, non-blocking. It essentially means a Node.js based server never waits for an API to return data. The server moves to the next API after calling it and a notification mechanism of Events of Node.js helps the server to get a response from the previous API call.
Node.js cuts down the overall processing time while uploading audio and video files. Node.js applications never buffer any data. These applications simply output the data in chunks.
Node.js is highly scalable because event mechanism helps the server to respond in a non-blocking way.
Node.js follows a single threaded model with event looping.
