Node.js is a server-side JavaScript runtime environment used for backend development, while React.js is a frontend library used for building user interfaces. Node.js allows executing JavaScript on the server, while React.js focuses on the view layer and provides a component-based architecture for UI development. To learn reactjs check out reactjs tutorial which provide complete guide.

1. Node.js is a JavaScript
runtime environment
that allows executing
JavaScript code outside
of a web browser. It
provides a platform for
building server-side
applications and
executing JavaScript on
the server.
Node.js is commonly
used for backend
development tasks such
as handling HTTP
requests, data
processing, accessing
databases, and building
APIs.
React.js uses a virtual
DOM (Document Object
Model) to efficiently
update and render
components. It updates
only the necessary parts
of the DOM, resulting in
improved performance.
Node.js is based on an
event-driven, non-
blocking I/O model,
which allows it to
handle a large number
of concurrent
connections efficiently.
This makes it suitable
for building scalable
and real-time
applications.
React.js is a JavaScript
library for building user
interfaces (UI) for web
applications. It focuses
on the view layer and
provides a component-
based approach to UI
development.
React.js allows
developers to create
reusable UI components
that encapsulate their
own logic and state. This
promotes modularity,
reusability, and easier
maintenance of complex
UIs.
Node.js enables
developers to use
JavaScript to write
server-side code,
making it easier to have
a consistent language
and toolset across the
entire application stack.
React.js enables the
creation of interactive
user interfaces by
handling UI state,
managing data flow,
and providing a
declarative approach to
building UI
components.
