This blog will explain how React Native apps can become more efficient and less complex with Hermes Engine and how React Native app developers who specialize in Javascript engines can take advantage of this powerful Javascript engine.

1. How Can the Hermes Engine Help React
Native Apps ?
Meta (previously Facebook) has decided to make React Native apps faster and
turbocharged using Hermes Engine, the default JavaScript engine.
This blog will explain how React Native apps can become more efficient and less
complex with Hermes Engine and how React Native app developers who
specialize in Javascript engines can take advantage of this powerful Javascript
engine.
Let’s first learn more about the Hermes engine and the updates to React Native
0.70.

2. What is the Hermes engine?
The performance of JavaScript frameworks began to decline as mobile apps
became more complex.
Facebook developed Hermes Engine in 2019 as an open-source JavaScript Engine
optimized for mobile apps.
React Native apps that are Facebook-centric were created with Hermes Engine by
Facebook to make them faster, more efficient, and more performance-oriented.
All react native apps become default users of the Hermes engine.
Facebook will make Hermes Engine its default JavaScript Engine starting
September 2022. As a result, react Native 0.70.0 has been launched to mark this
new development.
React Native 0.70.0 also includes several important updates, including:
 Codegen has a new, unified configuration.
 Android Full CMake Support
 New Architecture: Revamped documentation
 Android Auto-linking for New Architecture libraries

3. How can the Hermes Engine make Native Apps
respond faster?
JavaScript Engines used JIT, or Just In Time, to parse JavaScript Codes. This
provided quality assurance and application security, but it also slowed down the
process because JIT requires that the entire compilation be completed before the
application can fire the screens or functionalities.
This is possible with Hermes Engine because it uses ahead-of-time compilation
(AOT).
The AOT concept allows JavaScript Engine to perform heavy-duty tasks in the
background. As a result, the overall performance and usability of the application
are acceptable.

5 Reasons to Use React Js
React JS is today’s most popular JS library. Web developers are still using it even
after many years. It is the best JavaScript UI library to create and maintain views.
React is more than a library. It has JSX, Virtual DOMs, and other vital features.
JSX, or JavaScript Extension, combines HTML syntax and JavaScript to make it
easier for developers to interact with the browser.
Virtual DOM, a virtual copy of the DOM tree that web browsers create for keeping
track of real-time updates, is what React calls Virtual DOM.
We will now examine some of the other important React features in greater
detail.

1. React is easier to learn than Angular
React is a lightweight and elementary library that only addresses the view layer of
a webpage. React is easier to learn than JavaScript’s counterpart Angular.

7. React is easy to use if you have basic programming knowledge and a functional
understanding of HTML-CSS. It might take some time to adjust to React’s
innovative ways if you move from another framework.
React is easy to use and it’s easy to understand. You can find extensive
documentation online about ReactJS.
2. React has a large development community
React has a large following of JavaScript developers who create new tools and
solutions daily. Many user-developed apps have been added to the official library.
3. React Offers Reusable Components
ReactJS components are independent and reusable pieces of code. You can
provide input (props) if necessary, and the component will return an HTML
element.They can be used as a JavaScript primary function, a JavaScript class
component, or a JavaScript class that uses the render method.
You can reuse each React component you’ve created in another part of your app
or create wrapper parts that provide structure and reusability. You can continue
creating wrapper components from existing features until you reach a root
component.
Reusable components can cause system upgrades to be complicated, as each
change can impact the work of other members. React makes it easy to manage
updates because each part is isolated. Changes in one component don’t carry
over to the other.

4. Virtual DOMS
The Document Object Model, or DOM, is an interface that converts HTML and
XML codes into trees. Each object/element in the HTML code is treated as a node
within the DOM tree.
 The DOM tree must be rendered again whenever there is a change in the
HTML code.
 This can happen either through user interaction or value updates. This
causes a lot of power and time consumption. Virtual DOMs are where
ReactJS steps in to save the day.
 React creates a copy of the DOM and maintains a cache memory.
 React examines the VirtualDOM every time there is a change and pinpoints
which components and tree nodes need to be updated.
 The tree can be easily updated by making a minor change to the DOM. This
saves developers tons of time and makes the application responsive and
fast.
 JSX increases ReactJS’ performance and efficiency.
 Facebook created it to expand the functionality of HTML structures into
JavaScript. JSX does not require separate HTML or JS codes.
 Declarative HTML syntax can be used directly in JavaScript code using
ReactJS. To display the UI, browsers decode HTML files.
 JavaScript allows us to modify DOM trees to create interactive UI.
 JSX improves the efficiency of manipulating DOMs in manifolds.
 Developers can pass HTML and ReactJS elements in browser tree structures
and create clean, manageable code.
 JSX and the Virtual DOM increase the efficiency and performance of ReactJS
applications. JSX can also be used in conjunction with other libraries and
frameworks.

9.  Props are information that is inherited from a parent component in React.
Because React is a unidirectional data flow, props are immutable objects
that child components cannot change.
 You can modify an object by updating its state. ReactJS will alter valid
details automatically to preserve consistency.
 React’s unidirectional data binding provides greater control over
component data access and makes debugging and error-checking much
easier.
 To avoid access problems, it is essential to declare props in parent
components that fundamental values must be accessible and modified by
many elements.
5. React Hooks
Redux was the topic of much debate at the time that React Hooks was launched.
The answer is no. Hooks, a feature independent of ReactJS 16.8, allows JavaScript
developers to write states and other elements within function components.
The complicated classes don’t have to be dealt with anymore. You can also
collocate similar senses within a single part. And you can share data with other
parts without classes or props.
These are the main reasons React is a popular choice for developers. ReactJS is a
highly productive, structured, and performative library that offers many benefits.
The library offers robust features like virtual DOM, reusable parts, one-way data
binding, and Hooks.

10. What does React Native do to meet the specific
requirements of social media app development?
 React Native’s activity feed allows for the creation of dynamic news feeds.
It improves social media apps‘ user retention, conversion, engagement, and
engagement rate.
 React Native users can like photos and leave comments with emojis. Single-
page applications allow users to comment or like a photo or post. We all
know the advantages of React for building SPAs.
 Uploading photos is easy and fast.
 Chat apps that use real-time can use both client-side and server-side
libraries. React Native allows users to connect instantly with their friends
and acquaintances.
 Firebase authentication allows you to create login features with multiple
sign-in options.
 Push notifications can be integrated into the program by using the Firestore
database. Every social networking app must include real-time reports to
send messages and interact with friends’ posts.
 Firebase’s real-time database allows users to update posts in real-time.
 D3.js can be used to create a timeline that graphically represents the posts
on the map.
 Integration of the localization function to support multiple languages
Conclusion
React, a well-known JavaScript library that is widely used around the globe was
discussed in this blog. It is a highly-productive and easy-to-use JavaScript
framework that provides state-of-the-art functionality.
