Node JS Advantages
1- Easy Scalability
Node.JS is a lightweight technology and one of the key benefits of Node.JS is that it is considered to be the best option for micro-service architecture. Developers find it quite easy to scale the applications in horizontal as well as vertical directions. It becomes easier to add more micro-services on the top of the existing one.
2- JS is Easy to Learn
3- Used as Single Programming Language
4- Benefit of Full Stack JS
5- Offers High Performance
6- Large and Active Community
Node.JS Developers community is very dynamic and constantly contributes to the improvement and betterment of Node.JS and it is expected that we will witness more positive and absolute solution rich eco-system.
7- JS Offers freedom to Develop Apps
Another significant advantage of Node.JS is that it offers freedom to develop apps and software, unlike other imposing certain guidelines to developing apps and software.
8- Facility of Caching Single Modules
The open source run time environment of Node.JS single modules caching feature. The request from the first module gets cached in the application memory, allowing applications to load the web page faster and responds very smoothly to the end users.

1- API Not Stable
One of the major Node.JS drawbacks is that it does not have consistency. The API changes frequently and this increases the trouble of developers, as when it happens they’ll need to make changes in the existing code base to ensure the consistency.
2- Time Consuming
Developers need to write everything from the scratch and this is quite time consuming, hence to make your project glitch free, you need to hire experienced Node.JS developer to develop and maintain code.
3- Does Not Support Multi-Threading Programming
JS does not support multi-threading programming, it is not compatible with heavy computing app development.
Packed with advantages and disadvantages, Node.JS may not be a star performer in every area, but it is also not less than Java, .NET Framework or PHP. Node.JS development perfectly fits the need of app development for social networking, gaming, live chats, and stock exchange software or ad servers.
