Have you ever faced confusion between Reactjs and React Native, and which one would be better suited to accomplish your ideas? Or the similarity in their nomenclature has made you question the difference between them? Can they be used interchangeably? To find an answer to all these questions, let us take a quick look at the histories of these technologies, how they came into existence, and what purposes they solve for programmers across the world.
Today Reactjs and React Native are at the core of numerous websites and apps that are widely popular and have grown into mammoth enterprises. One such enterprise is Facebook (now Meta) itself. The year was 2011 when Jordan Walke, an engineer at Facebook, created the prototype of what we know as Reactjs today. It was first deployed in the Facebook news feed and then on Instagram. The need to develop new technology for the Facebook app came because of decreasing efficiency caused by constant updates.
On the grounds of these developments, the inception of React Native took place. After months of constant tinkering and development, the first version of this open-source UI framework was released. Hence, both these technologies are developed and controlled by Facebook.
Reactjs brings superfast speeds to developed applications and websites using the Document Object Model (DOM). A data structure cache is created by React; this in-memory cache computes the resulting differences and then smoothly and swiftly updates the browser’s displayed DOM. The code written by the programmer is that the whole page gets rendered based on each change, but in actual functioning, only those components that are subject to change undergo rendering. This gives an added edge of speed to React, which is instrumental to developing any type of application.
As mentioned above, Reactjs is capable of server-side development, and this backend capability brings an edge to the Search Engine Optimization of the web pages. To index and cache the content of a webpage, a search engine bot has to visit the server. When all the content and visual assets, such as images or videos, are already rendered on the server, it becomes easier for the bot to do its task of indexing and further make the ranking process faster. Hence, Reactjs gives an added advantage to businesses and websites due to its enhanced SEO process.
Direct rendering from the server also reduces page load time, which enhances the user experience to several notches.
One thing that helped React create such a great impact in the industry was its concept of reusing components. Through this component-based architecture, unit pieces of an extensively large user interface are turned into micro-systems that are not dependent on the bigger system.
Think of an application with a large UI, like Paypal or Facebook, to understand better. Whenever any component within a certain section of the interface needs to be redefined, it can be accomplished without interfering with the whole interface of the app.
Reactjs has a massive and dedicated community of developers who keep adding to the already extensive ecosystem of component libraries, extensions for code editors, tools, IDEs, etc. When such a wide range of tools and third-party extensions are available, the scope for innovative problem solving and development increases manifolds. These facilities are rich from a development point of view and save a lot of time when working with common components and extensions.
The component-based structure of React Native lets the developer build apps in a more agile process than a majority of the hybrid frameworks, which happens without any web.
React Native lets you (the developer) generate platform-specific code for your app or website, and it is one of the most valuable propositions of this framework. This is an automatic detection process where the framework itself catches the platform it runs and generates the code for the right platform.
Despite some similarities in both the technologies, Reactjs and React Native has some noteworthy differences:
React is apt for creating high-performing dynamic web interfaces and has a responsive UI to put things in perspective. Whereas, React Native should be your go-to for building mobile apps with a truly native feel.
Despite being groundbreaking in their respective capabilities, both Reactjs and React Native have their own sets of drawbacks.
And if you have read till here, you must have understood that both these technologies are cornerstones of the web and app development world. It is also quite evident that both of these solve varying degrees of purpose. As a developer, you must choose one after carefully analyzing which one fits your needs and ideas better.
