Why Node.js? 

I want to discuss in details about why Node.js? since you are new to node.js, you need to know why it is popular?

In the past Javascript was mainly used for client side validation. So front end developers will develop code with HTML, CSS and javascript combo and backend developers will use Java, PHP or some other server side programming language.

Usually there will be more problem when you are using different language for frontend and backend? Do you agree with me?

Prominent problem will be communication gap between front end and back end developer ?

Front end developer doesn't have much knowledge about back end. how code designed and data handled at the backend.

To overcome the above problem, Node will be helpful, you can write front and backend code with Javascript Language.

Using javascript you can write frontend and backend code, Learning javascript is an easy task when compared to any other programming language. For front end, you can use angularjs, reactjs or any other client side javascript library and for backend you can use Node.

Now you can understand, how node became popular in short time.
