1), real-time applications: such as online chat, real-time push notification, etc. (such as socket.io)
2), distributed applications: with efficient parallel I / O using the existing data
3), application tools: Mass tools, small compression distal deployment (e.g. Grunt), large desktop GUI applications
4), game type applications: gaming concurrent real-time requirements and a high (e.g., frame NetEase pomelo)
5), using the Web to enhance the stability of the interface rendering capabilities
6), front and rear side programming language environment unity: front-end developers can very quickly cut into the server-side development (such as the famous pure Javascript MEAN full-stack architecture)
