what the difference between react native and react js?

Rract js
ReactJS is an open source JavaScript library that is used to create the user interface of Web Applications. It’s solely responsible with the visual layer in the app. It lets developers create complicated UIs with a small, isolated piece of code referred to as “components.” ReactJS is comprised of two parts. first are components, which comprise HTML code and the information you’d like to see on the user interface. the other is an HTML document, where all of components are rendered.
Jordan Walke, who was an engineer for software at Facebook who developed the software. It was initially developed to be maintained and updated by Facebook and later was incorporated in its applications such as WhatsApp & Instagram. Facebook created ReactJS in 2011 to support the newsfeed section. However, it was made available to the general public in May 2013.

Advantage of ReactJS
⦁ Easy to learn and use: ReactJS is much more simple to understand and use. Anyone with an JavaScript background is able to understand and start developing web applications with React.
⦁ Making Dynamic Web Applications is now easier: To create a dynamic web site specifically using HTML was difficult, as it calls for complex programming, however React JS solved that issue and makes it much easier. It is less code-intensive and provides more features.
⦁ Reusable Components: ReactJS is a web-based application that comprises multiple components. Each component is controlled by its logic and control. They can be reused whenever they are needed. The reused code helps simplify your applications to create and maintain.
⦁ Improvement in Performance: ReactJS improves performance because of virtual DOM. The React VirtualDOM runs entirely in memory , and is an exact representation of the DOM used by web browsers. This is why the fact that when we create an React component, it is because we do not directly write to DOM. Instead, we write digital components which to transform into DOM which results in more fluid and quicker performance.
⦁ The support of handy Tools: ReactJS support the use of a set of tools that make the work of developers clearer and simpler. Additionally, it allows you to choose specific components, and then look over and change their current state and Props.
Disadvantage of ReactJS
⦁ The speed in development: It is well-known that the frameworks change rapidly. Developers aren’t feeling at ease with the new methods of working regularly. It could be difficult for them to adapt to the changes in all the regular updates.
⦁ Poor documentation: React technologies are constantly evolving and growing so fast that it is impossible to write adequate documentation. To combat this issue, developers write instructions by themselves, based on the constant evolution of new releases and tools they use in their current projects.
⦁ View Part: ReactJS only covers the UI layers of the application and it does not cover anything else. This means that you need to select other technologies in order to have the complete set of tools for development of the app.
⦁ SEO-friendly: Traditional JavaScript frameworks face a problem when dealing with SEO. ReactJS solves this issue by allowing developers to be easily found through different search engines. This is due to the fact that ReactJS applications be run on a server while the virtualDOM can render and then returning to the browser in the form of an ordinary web page.
⦁ The advantages from Having JavaScript Library: Presently, ReactJS gaining popularity among web developers. It provides a extensive JavaScript library that gives more flexibility to web developers to pick what they would like to do with their.
⦁ Scope to Test The Codes: Applications built with ReactJS are simple to test. It provides a space where developers can examine and test their code using native tools.
React Native
React Native is an open source JavaScript framework that is used to create an application that runs on mobile devices such as iOS Android, and Windows. It relies on JavaScript to create an application that runs on all platforms. React Native is the same as React however it makes use of native component instead of web components to build. It is targeted at mobile platforms more than the browser.
Facebook creates React Native in 2013 for its own internal project Hackathon. In March of 2015, Facebook announced that React Native was open and accessible via GitHub.
React Native was initially developed to support initially for iOS application. Recently, however it has also been added to it for the Android operating system.

Advantages of React Native
⦁ There are many advantages to using React Native for building mobile applications. A few of them are described below:
⦁ Cross-Platform Usage It gives users the option of “Learn one time to write all over the world.” It works on both platforms Android and iOS devices.
⦁ class performance: Code written using React Native are compiled into native code, enabling it to work on both operating systems, as well as performs the same across both platforms.
⦁ JavaScript: JavaScript knowledge is used to create native mobile applications.
⦁ Community A large and diverse community that includes ReactJS as well as React Native helps us to get any solution we need.
⦁ Hot Reloading Just a couple of modifications to the code of your application will be visible immediately while developing. If the business logic has been modified, its reflection is live reloaded onto the screen.
⦁ Enhancing the quality of HTML0 with Time: Some features of iOS and Android aren’t yet fully supported, and the community is always coming up with the most effective methods.
⦁ native components: The developers will have to code a platform specific code to build native functionality that isn’t yet designed.
⦁ Existence is uncertain: As Facebook develop this framework, its future is uncertain as it holds the right to take it away off the project at any time. As the demand for React Native rises, it is not likely to occur.
Disadvantages of React Native
⦁ React Native is still in its initial stages and in its infant stage: The React Native is a brand new feature in Android or iOS programming languages. It is still in the process of improving that could negatively impact the applications.
⦁ Learning is difficult: React Native is not an easy subject to master particularly for someone who is new in the field of app development.
⦁ It’s not secure robustness: React Native is an open-source JavaScript library and an open-source framework that creates gaps in security robustness. If you’re developing financial or banking apps in which sensitive data is required experts advise not to select React Native.
⦁ It requires more time to Start: React Native takes quite a long time beginning the runtime process, even for the most advanced devices and gadgets.
