Pros and Cons, Features of ReactJS Development
Everything you must know about ReactJS
ReactJS is an open-source JavaScript library that helps develops to create easy User Interface for the webpages and mobile apps. The Library contains the set of codes and statements that helps the developer to use while creating attractive and navigable for users.
However, ReactJS is mostly used to create UI for single page websites and mobile apps. It provides steps of codes for the upper view layer of the app. The library scripts are reusable and can be applied to many circumstances.
ReactJS is a frontend library that runs on a browser with many kinds of the old webserver. It works as efficiently as any other frontend library like jQuery. However, it is to be noted that React.js is not a framework and should not be mixed with the MVC Framework.
7 Top Features of ReactJS
Simplicity
The first best feature of the React is its simplicity. The API of ReactJS is so simple and yet powerful. So when it comes to designing software for the developers, just borrow code from the free access of React and use it in the programming. React.js is the library with the JS functions which produces HTML and CSS codes. With a few basic functions, developers can create intuitive UI for the web application.
Proclamation of Codes
ReactJS helps the developer to create a very interesting and manageable user interface for applications. Reactjs developers can create a simple view layer for the application and React will adjust the codes and changes as per the latest codes updated in the library. Since the codes in the React library are very descriptive and declarative, developers can review the codes and fix the bugs easily.
Corresponding Virtual DOM
ReactJS saves the time of the developers and testers by creating virtual DOM Objects for every DOM object created in the library.
The Virtual DOM is the replica of the DOM. Hence, whenever, the developer wants to modify something in the DOM object it can directly do in the virtual DOM. It saves time and effort for the developing team.
Data Binding
ReactJS has a one-way data-binding system which means that data flows in one direction only. The parent component passes the data to the child component. The one-way data binding feature helps the developers to get better control in the flow of data and helps in fixing the bugs. The codes of data cannot be sent back to the parent component.
ReactJS supports JSX
JSX is JavaScript syntax which is very similar to HTML tags. Most of the codes in the ReactJS is written in JSX. Since JSX syntax is the combination of JavaScript and XML, the developers can easily search n write the components by using the feature.
Conditional Coding
ReactJS gives the power of conditional coding to react developers in the JSX syntax. The developers can create conditional coding and components in the library which helps them to offer great UI experience with changing scenarios.
Pros and Cons of ReactJS
React.js is a highly effective way to create beautiful UI for the apps and also enhance the speed of the applications. Here are some pros and cons of React which is observed over time.
Pros of ReactJS
Easy to Learn
ReactJS is very easy to learn and understand especially if a developer has a background of Java, it can learn the React.js very easily and implement the codes in the development.
React comes with fully functional tutorials, documentation, and training materials. React is the View part of the MVC model of the JavaScript framework.
Easy to Create
ReactJS offers the developers to create dynamic web applications interface which not only increases the usability of the apps but also increases the speed of the same. React helps the developers by providing readymade code sections for the development of UI and saves their time.
Reusable
The components of the React have their logic and control. The developers can use the multiple components many times, hence making the React.js easy to use and modify. The concept of Virtual DOM Object creates data for the HTML DOM which is easy and does not require changes in the actual DOM every time.
Ability to Control Data Flow
With the one-way data binding features, ReactJS offers greater control over the flow of data for the developers. Wince the child components cannot affect or modify the parent component; it becomes easy to have an easy and manageable view model for the applications. so, to make changes in the object all developers must do is modify the state of the object and run an update.
Development due to Open Source
ReactJS is the first open-source project with the JavaScript Library; hence it enjoys all the free access and development in the library. Many giant companies and big developers have used the Reactjs development for the application which made it highly resourceful for small developers. There many additional tools from the off-company developers which have contributed to the usefulness of the components.
ReactJS is SEO Friendly
Many JavaScript components in the past have been difficult to read SEO guidelines. Many developers complain that the Java Scripted applications are not been read by the search engines completely. But with React JS the problem of SEO is solved.
The scripts in the React JS are readable and can be optimized for search engines. The easy mechanism of React app uses server-side rending while Virtual DOM communicates with the web browser like a regular website.
Huge JavaScript Library
Since Reactjs is the open JavaScript Library it offers thousands of the Java Script components which can be used by the developers repeatedly. Most of the web developers use the ReactJS JavaScript Library for flexibility in the designing of the web page and applications.
Testing is Easy
ReactJS has the native tools that help the developers to test the components before using them. The web developers can test the components and fix the bugs easily with the React.
Cons of ReactJS
Constant Changing Components
Reactjs is the open-source JavaScript library that enjoys all the features of free access by many web developers across the globe. This leads to rapid changes and updates in the library. Many web developers are not comfortable with the rapidly changing, as it creates issues with the running of the scripts in the UI. Sometimes, constant and rapid development causes real problems with developers.
Lack of Documentation
Since there are constant changes in the ReactJS with the free access to the library, the documentation takes the back seat. Many developers are just using the codes and modifying it without following proper documentation guidelines. The developers use the codes and modify and update the releases for the current project. Hence, lately, React is facing poor documentation problems.
Incomplete
ReactJS is just the View part of the MVC Model. Hence, it can just be used for developing the UI of the software or website. It is not a comprehensive tooling kit for developing software. Many developers find the library just a single-use tool.
Usage of JSX
Since the ReactJS uses the JSX syntax which is the combination of the JavaScript and HTML. Many new developers find it difficult to understand the component. However, according to them, it takes time to understand the code with JSX syntax.
Why ReactJS?
There are many open-source platforms available these days which helps the developers to create attractive and useful web applications like Angular. There are tons of features offered by the ReactJS library which can be used by the web developers to create a view layer of the application.

Not every project can use the Reactjs library sources. Many companies are using React only when they need to use the library with the flux pattern library like Redux and MobX. However, of the application is simple and small, developers can easily write lines of codes in the JavaScript without need for use of ReactJS.
One of the features of ReactJS is the ease of modifying and testing ability. So if the project entails the need for the designing that upgrades the codes as per the changing needs of the users or requires a large set of inputs from the user, user logins, and access permissions, then React may be a good option for the developers to use. The library offers dynamic web designing features to the developers which can be used in the changing environment.
When to use ReactJS and When not to?
ReactJS is a pure JavaScript based open-source library. Hence, there is an absolute need for JavaScript knowledge from the developers using the library components.
- If the programming and designing team consists of developers having JavaScript background and possess knowledge in the field, using React.js is practical and easy for them. However, the team also needs to understand the JSX syntax codes and should be able to work with the components in the Reactjs library.
- In most of the cases, it has been noticed that designers who are conversant with the HTML tags are not very conversant with the JSX syntax, which makes the use of the ReactJS limited and redundant. For better use of React, the developers must also know of CSS and layer design.
- Although, ReactJS is changing and evolving with time and free access, the shortcomings of the library components will soon extinguish, and more and more teams will be using React for the web application UI. With time and date, React.js has shown a better learning curve even for the newbies and old-time developers.
Conclusion
Finally, ReactJS has proven that the use of the open-source library in the JavaScript framework is somewhat useful for any kind of web developer.
Whether you are a company or individual developer, React has a huge number of native tools to make web application designing fun and intuitive. There are developers’ tools and active support from the engineer’s backend of the library. It’s growing and evolving at a very fast pace.
Nowadays developers don’t need to write the same set off codes again and again. With the use of ReactJS, developers can focus on the testing and running of the codes rather than writing detailed line codes for the view part of the application. Reactjs does also has an active online tutorial that developers can use to learn the application of Reactjs components to the software.
