Features of Node.js
Node.js is extremely scalable because that server responds in non-blocking way.
When the open source tribe supports the Node.js. This is the only reason to over the time that many marvelous modules have been added to Node.js applications.
Event driven input and output
Non-blocking of APIs to the Node.js. It means API are not return to the data of server are not waiting. Instead moved to another APIof server.
Node.js are no time buffer the data of applications. They only the statistics in large pieces.
Node.js follows a single threaded model with event looping.
What is Express.js?
Express.js is a small Node.js framework of web application. It provide a potency set of topographies for both mobile and web applications. Node.js foundation has offered an open source framework with Express.js. When the applications created by trifling interface in which delivered by Express.js. It provided you the implements that are compulsory to build an app. When the Express.js are directly persevered, because it’s elastic in a way that there are many components accessible on package manager.
Features of Express.js
Page state retention

Express.js uses many Node.js features to call functions anywhere. Node.js can be written I less number of lines and in a few minutes, because many multifaceted tasks that take numerous lines of code and hours of programming.
Errors and bugs in any application can cause whole application can be breakdown. The identification of task is very crucial. Express.js provide an easy mechanism, which are the application is causing bugs are let you quickly located.
