You Use ReactJS:
A Complete
Guide

2. What is ReactJS, its advantages & why should you care about it? If you are
wondering the same then this PPT is for you. React, which was originally created for
Facebook, is a JavaScript package that creates user interfaces for single-page apps by

Here Are The Reasons Why Use ReactJS
React has a component-based architecture. Each component determines
how it is to be presented. Each component is governed by its own set of
guidelines. You can reuse components anywhere you need them.
Components that can be Reused
Updating the DOM is frequently the bottleneck. React is tackling this
issue by utilising virtual DOM. Finally, the changes are applied to the
DOM to provide the shortest possible read/write latency.

Here Are The Reasons Why Use ReactJS
Facebook created and maintains the Flux architecture, which they
employ for their web apps. To update stores, the primary idea is to
construct activities that are orchestrated by a central dispatcher. The
views are then changed in response to changes in the stores.
Flux and Redux
One of React’s most powerful features is that it provides good
abstraction, which means it does not expose any sophisticated internals
to the user.

Advantages of ReactJS Development
ReactJS is popular among developers because it is efficient, declarative,
and flexible. What’s more fascinating, learning React is simpler than
learning other JavaScript frameworks.
The Learning Curve for React is Steep
Another incentive to choose React is its flexibility, which presents itself in
a variety of ways. The architecture of React enables the bundling of front-
end code into custom components, offering a solid foundation for overall
development process optimisation.

Advantages of ReactJS Development
Front-end development with React results in solutions that are not just
performant but also highly testable.
React Create Rich User Experiences
Everyone would prefer to have a tool or two that could help them improve
their productivity. ReactJS has a library that can improve developer’s
performance and is widely on par with Angular in this regard.

Advantages of ReactJS Development
Making your web app or site crawlable by search engines is one of the
most efficient strategies to boost it. The fact that React uses JavaScript to
load pages in most cases is a huge bonus.
ReactJS can be useful for SEO
As an open-source library, ReactJS has what it takes to continuously recruit
newcomers to its community, which only strengthens it over time. The
React library has entered the growth loop and appears to want to stay
there for as long as possible.
React Developers Get Widespread Community Support

8. Other JavaScript Libraries vs. ReactJS
React Native is a sophisticated
mobile framework that
employs React ideas to create
native-looking apps. It
develops hybrid cross-
platform applications using
only JavaScript and HTML.
The developer has complete
control over ReactJS. It can be
used to create SPAs, mobile or
hybrid apps, and even a TV
application. ReactJS will
optimise the performance of
your app.
React does not use an MVC or
MVVM architecture. It is up to
the developers to select the
best architecture for
constructing web apps. For
integrating the entire MVC
architecture with React, you
can use web frameworks such
as AngularJS or BackboneJS.

9. ReactJS is ideal for SPAs since these sites constantly refresh their content based
on data from web servers. The feature-rich library can expertly handle the tough
content update process.
Single Page
Applications
React allows a component-based approach to designing applications with a
variety of workflows and extensive server-side logic.
Large Scale
Objects
React simplifies the process of applications where there are major complexities
regarding performant UI.

12. Conclusion
Front-end web development with React was a
prominent trend in 2021 and will continue to be
so in 2022. The evidence supporting this claim is
unequivocal. Since its initial release, the React
library has been constantly expanding and
improving.
