This article is aimed to figure out the prehistory of React creation as well as to find the pros and cons of utilizing React techs.
The essence of React
Before ReactJS has become available for multiple users, the biggest challenge of Facebook was to create fast-moving and productive UI. For instance, the developers required the possibility to enable adding fresh news into the newsfeed at the same time when the client was modifying personal data profile or talking to the friends in chat.
A couple of years after that the same team delivered React Native, a combined framework for mobile applications creation for iOS and Android operational systems. The core technologies of ReactJS and Reactive Native are basically the same, therefore, the developer's societies as well as software companies, the priority of which is specifically mobile format, have adapted themselves to it rapidly.
Below you are suggested to review the strengths and weaknesses of ReactJS. After that, the analysis of React Native’s dissimilarities, its positives, and negatives derived from ReactJS will be proposed.
Strengths of ReactJS
1. Virtual Document Object Model improves UX and facilitates coding
DOM is the rational formation of the files in multiple formats such as HTML, XHTML, and XML. In the dilettante’s words, it is the outlook tree-structured arrangement of data entries and outs. The blueprint gears are utilized in browsers to change or to disassemble the image HTML-pattern into DOM that can be observed in the browser.
The principal issue related to conventional DOM building is the method of transformations treatment, for example, customers’ inquiries, requests etc. The server continuously conducts the monitoring of the distinctions that appeared due to these alternations in order to submit the required reply. In order to provide the relevant answer an upgrade of the tree-type structures of Document Object Model throughout the file is required, that is not easy to do as the DOM trees are rather expanded these days and consist of multiple constituents.
The group of developers in charge of React achieved the increase of velocity of updating the system with the help of virtualized Document Object Model. In a simple phrase, as long as other frameworks approach practically existing DOM, their newest competitor, ReactJS, exploits the non-figurative model, the virtual one. It allows renewing the tiniest alternations, submitted by the customer while the rest of interface components remain unimpaired. This can be achieved because of the encapsulation of React’s elements and exclusive scheme of data arrangement within the boundaries of the library.
It conducts the updating process promptly, therefore it is possible to design an extremely swift UI. It can be observed in the aforementioned situation when the client is able to change personal information profile and get more news simultaneously. Furthermore, in the case of ReactJS, the coders shouldn’t connect the Document Object Model with the operational content placed in the front-end as the components of React have been already associated with it.
This method helps the coders to deal with UI-modules at a higher rate and to employ urgent reload, i.e. bringing the transformations into immediately. Thus, it enhanced the productivity and raised the coding velocity.
2. The repeated utilization of the code elements
Another advantage of React is the possibility to repeatedly exploit the elements of the code on any stage at any given point in time. This feature helps to reduce the time required for coding.
Basically, reusing the available components is an effective practice that is proved by the web designers who achieve significant time-saving results when applying the same pieces and modules within various projects. Yet, in terms of coding the situation is more complex. The updates of the system can be really challenging as every even small transformation may influence the functioning of other elements.
3. The single-oriented data stream in ReactJS produces substantial code
ReactJS ensures straight access to the elements and exploits descending data associating method to protect the higher level configurations from being transformed when the lower level structures are being modified. It allows getting the balanced code.
More complicated observation-type arrangements of JS-configuration are characterized with tangible weakness: schemes of data streams. Actually, the low-level elements may influence the higher level ones when being altered in JS view model structures. In the case of ReactJS, the vendor has eliminated these negatives by leaving it as just the viewing structure.
As a substitute for applying clear data association, ReactJS prefers utilizing single orientation model, a descending data stream. That’s why the lower level components don’t affect the lower level ones. Consequently, everything the coder should do is to change the status of the element and to add the updated fragments. As a result, solely the authorized constituents will be amended.
4. Library with the publicly-available code: more progress, more improvements
Weaknesses of ReactJS
1. Extreme development velocity
The problem is that coding landscape is being altered too fast and the developers have to always and get used to the updated methods and patterns. Consequently, many coders are not able to cope with such high velocity.
2. Insufficient level of documentation available
The heart of the problem is the continual issuance of the upgraded instruments. Various cutting-edge libraries such as Reflux are aimed to facilitate functioning and to advance the whole ReactJS environment. However, the coders often have difficulties when implementing new instruments into ReactJS. For instance, some societies of developers believe that React solutions are being upgraded so quickly that there is too few time to create sufficient working manuals. In order to revolve this complicacy, the coders have to create special instructions by themselves for the individual instruments being employed in the ongoing projects.
3. JSX makes it tough
The distinction between ReactJS and React Native
The chronological gap in the release of ReactJS and React Native is two years, however, this is not the biggest issue that makes them different. Basically, ReactJS was created to develop web interface while React Native is a mixed-type framework for developing the applications for iOS and Android mobile operating systems. The good news is React Native derives the majority of concepts and patterns from ReactJS.
As a matter of fact, the most tangible variations between the two products are related to the purposes of the platform.
- As long ReactJS exploits Virtualized Document Object Model for rendering the code of a browser, React Native takes advantage of original Application Programming Interfaces that serve as an adapter for rendering the elements in the portable format. For instance, React Native embraces the Application Programming Interfaces of Java and actuates Objective-C API’s module to shift to iOS.
- There is no HTML involved in React Native. Therefore, it may take some time and efforts for you to get adjusted to React Native patterns if you used to deal with ReactJS before.
- As long as React Native avoids utilizing CSS, the CSS-based elements can be launched only with the help of special Application Programming Interfaces.
Strengths of React Native
These days React Native is acknowledged to be one of the quickest and productive spaces for creating mobile applications. In a layperson’s terms it is very similar to ReactJS but in a mobile format:
Sometimes the follow-up updating can be even accelerated, e.g. iOS ensures functionality of the JS-related transformations of the apps in an online regime without the necessity to observe the circuit.
2. Original monitoring features and elements in React Native: the productivity reinforcement factor
React Native transfers the range of code elements using native Application Programming Interfaces as contrasted with other frameworks, for example, PhoneGap that shifts the code elements through WebView. As WebView negatively impacts the through-put, React Native access the required modules of iOS and Android, transferring the data to the original API straightly. This method also includes the individual fiber connecting UI that improves the results too.
The importance of original modules can’t dine anyway. These days React supplies the developers with the kit of native modules on Java as well as in Objective-C. It is impossible to repeatedly utilize them throughout two OS, however, they are useful for increasing productivity when dealing with complex solutions such as a photo or video processing. What is important, you are able to operate with the available modules or to create specific individual modules by yourself. The expansion of React developers’ societies positively influences the availability of public features when the remaining part of the code is not permitted to be repeatedly employed. For example, Facebook Ads Manager distributes almost 90% of the code in the iOS and Android environment.
Furthermore, React Native ensures easy bugs elimination and error notification instruments availability. Therefore, the developers are able to employ the development facilities of the most popular and well-known browsers, for example, Safari or Chrome.
3. React Native have inherited all ReactJS characteristics that make UI better
As React Native derived multiple features from ReactJS as from JS library, it also takes over the primary benefits from it. In order to design the multiple platform application using React Native, the understanding of the original stage language is not required. The only thing they have to know is JS and React basic patterns. If necessary, it is always possible to supplement the code with native elements.
In React Native the descending data stream model is reproduced, thus, the high-level elements are modified without changing low-level ones. This approach helps to polish the procedure of UI development, so the applications seem to be more native.
Weaknesses of React Native
1. Availability of the documents
Sadly, React Native has the same problem as ReactJS. The society is at the early stage of its development, so quality and availability of the necessary manuals are low, in particular, what concerns associating React Native with supplementary instruments.
2. Proficiency in native modules
Undoubtedly, the native modules play the positive role in coding by providing a framework with extra variability and helping out the system in case of lacking some performance. The developers often exploit the original modules when dealing with complicated objects.
Yet, at the same time, it may negatively impact the multiple-platforms development stage because the team will require additional engineers focused on native modules just in case.
3. The elements involved from the outside
The vendor declares that it possesses the range of original modules for Android as well as for iOS, taken from the outside environment, however, the quantity of such elements is insufficient. At the same time, there is no guarantee that in-house created modules will remain valid in the further updates of the framework.
4. Leaving off SDK amendments
It is a well-known fact that React Native often back-pedals when SDK is upgraded by Android or iOS. The thing is the React Native development group have to associate the library with the latest software. Although these processes are conducted quickly, they are not able to amend each segment of Application Programming Interface simultaneously. This is a cause why the complete integration of React Native with latest versions of SDK is so slow.
The famous & successful cases of ReactJS and React Native implementation
Obviously, in terms of world-known projects, React JS is a leader being a key technology for such distinguished startups as Instagram, that aimed to make both web and mobile apps to get more users, Netflix, that is utilizing it along with Gibbon, and Airbnb, that shifted to ReactJS due to code reorganization simplicity and the possibility of its elements repeatable use. In turn, React Native was integrated by Bloomberg when creating the mobile application for a web magazine, and it stands to mention that Bloomberg seems to be really excited about having this technology.
In the context of productivity React is really sky-rocketing tech taking into account its progressing popularity in the developers’ societies and among the businesses that starting using it. As long as most of the other frameworks enhance user interface by increasing software effectiveness, “green as grass” and sometimes puzzle-headed React Native thrives into the transformation of the method for associating the application with the software as well as hardware. At the same time, ReactJS proposes outstanding possibilities in front-end web development improvement and upgrading.
