Answer 1

Programmer Raja (தமிழன்) hi,
Node is a runtime environment for backend purposes.
Among other things you'll have to learn,how to create a server, http requests, how to handle them,Ajax, as well as modules, how to import them and use them(npm and cli)...
To build a complete app, you'll need to know how to articulate all those things in the node environment...
