MEAN is a full-stack JavaScript framework which ensures rapid development with high efficiency. Mean stack is a JS based technology stack comprising of four pillar MongoDB, ExpressJS, AngularJS and Node.JS.

With React Native we can develop Android and IOS native apps using Javascript. React Native helps us to develop cross-platform apps in shorter duration. One of the main advantages of React native over other hybrid Mobile App development platforms is reacted native creates the components in native platforms and is able to provide the closer performance of native apps. React native reduces the overall development time considerably.

Node.JS is used in the server side and is built on the Google Chrome’s V8 JavaScript runtime which helps in building concurrent, scalable and optimised applications. It uses a non-blocking, event-driven I/O model which is lightweight, enabling it to handle a large number of concurrent transactions efficiently. With Node Js we can do multiple tasks asynchronously with high performance. We have developed efficient Node JS based applications with less than 30ms latency.
