Node.js offers great speed
Widespread presence in servers and browsers
Efficiency in data streaming
In web platforms, the HTTP requests and the HTTP responses are typically considered as two separate events. However, in reality they are both data streams. Such a feature can be used with Node.js for processing files during the time of uploading. This can help to bring down overall processing time while dealing with data streams. The same strategy can also be applied for real-time audio or video recording.
Developing real-time web applications
With the help of Node.js, it is perfectly possible to real top quality real-time web applications at high speeds. The suite that comes with Node.js can help greatly in creating web apps like chat apps and games that can be used in real time by multiple users.
