In order to understand how competitive gains can be achieved, it is important to understand what makes Node.js so unique and powerful.
Node.js provides a module-driven, highly scalable approach to application design, development and deployment that enables development teams to put the most desirable elements of agile methodology into practice. This can greatly reduce risk and raise developer productivity—raising developer morale in the process.
We don't have to worry about how Node.js is going to scale, or if it is going to be reliable.
