What is React? History of Creation and Prospects for the Future

ReactJS was developed by Facebook as a front-end JavaScript library for building user interfaces and was open-sourced in 2013. This framework popularized the concept of web development known as component-based architecture, which has numerous benefits, some of which include:

• Components are modular and coherent, which makes them highly reusable, contributing to a faster development time.
• Easy maintenance and upgrades due to self-contained components.
• Allows developers to reuse an application's logical section by simply changing the view.

React immediately swept the market, quickly overtaking most of the frameworks available at the time, including AngularJS. ReactJS uses a declarative style of programming to describe the UI state. The framework allows developers to figure out how their application will look for users and how they would interact with it. React is also used for building web applications, native-rendered apps, and mobile applications.

In addition to reusable library code, which saves development time and reduces the chance of coding errors, React comes with two other key features most developers love - virtual DOM and JSX. We’ll review them later on. React is an open-source project, allowing anyone to download and modify its source for free. Its libraries range from collections of individual UI features to complete React.js templates, allowing developers to build UI’s from scratch.

According to the Stack Overflow Survey, React was the number one web framework used by software developers worldwide in 2021 but, according to the data provided by Statista, in 2022, this framework was overtaken by Node.js, with 47.12% of web developers using this framework against 42.62% of React users. React is predicted to lead the way into the future, with 1,207,584 React websites currently live on the web and a 184%-increase in the number of open positions for React JS programmers in the post-COVID period.

React usage by websites across the globe:

Analyzing the job market for React and Angular technologies over the last three years, it can be seen that React technology is more on-demand worldwide among companies that decide to hire software developers.

The interest in React.js doesn’t fade with businesses continuing to invest in advancing this framework and ancillary resources. In December 2020, the Vercel company invested $40 million to advance the React framework. For the moment, ReactJS has a competitive edge over other leading frameworks like Angular or VueJS and is expected to be a global game-changer in the future with the increasing demand for front-end React developers.

Disadvantages of Angular. When to Avoid Using Angular?

The following are some disadvantages of utilizing Angular:

• Angular can be perplexing for newcomers.
• The learning curve is steep.
• There isn’t a clear manual or comprehensive documentation.
• Limited Routing makes it challenging to debug scopes.
• Third-party integration is complex.
• In some cases, Angular can become slow with pages containing interactive elements.
• Some issues may occur when switching from the older versions to the newer ones.

Angular is a complete dynamic solution as a framework. If you want to build small-scale web apps, you may not want to opt for Angular as you would not utilize its resources to the best, and it will be a misuse of time and resources. Also, Angular isn’t the best option if you’re a new developer with a small team or are creating a complex UI from scratch and don’t have time for a longer learning curve.

Advantages and Use Cases of React

The benefits of utilizing React are the following:

• The framework is simple to learn because of its component-based approach, use of plain JavaScript, and well-defined lifecycle.
• The React supports special JSX syntax that allows the creation of templates.
• Extensive and highly-detailed documentation.
• The library allows users to migrate between versions.
• Enhanced server-side rendering capability makes React a robust framework for content-focused apps.
• Skills learned in this framework can be applied to Native development.
• Developers can spend more time writing modern JS and less time worrying about the framework-specific code.
• React follows a unidirectional data flow. When building a React-based app, developers commonly “nest” child components within the parent components. Because the data then flows in one direction, it's easier for developers to debug errors and figure out where the source of the problem is in the code.
• Facebook has a “codemod” feature that automates much of the process.
• Combined with ES6/7, React framework is ideal for easily handling huge workloads.

The business benefits of this framework include:

• The reduced overall cost of web development. React features reusable components that significantly save developers time as they don’t have to write different code for similar features. Instead, they can utilize individual parts of the app on both the server and the client side. It boosts the speed of the development process and helps to reduce the overall costs of the web development process.
• Strong community support. Being one of the most popular frameworks for web development, React has a huge community, which helps to resolve issues faster, offering ready-made solutions to most problems developers may encounter during the process.
• Virtual DOM speeds up the loading of business apps. React uses a process called tree reconciliation, in which it first uses the virtual DOM to render an HTML tree virtually. Whenever the state changes, developers get a new HTML tree, and the library will write only the difference between the new and the previous tree, making the process faster. Virtual DOM improves the performance of highly loaded apps and UX.
• React-based apps are more SEO-friendly. With its fast rendering capabilities, React reduces the page loading time, helping businesses rank higher on Google SERPs and reducing bounce rates.
• Easy maintenance and updates. The reusability feature of React makes code manipulation more manageable and provides a much better look at the app code, making it more scalable.

A wide range of React use cases paired with its simplicity, component reusability, and singular direction of data flow makes coding and creating new projects much simpler than with many other technologies. Its well-known use cases include The New York Times, Netflix, Instagram, and Khan Academy.

• React is mainly used for developing single-page apps. The reusable components of this library make it an excellent choice when you require building an interactive interface for an application within a limited time. As for the types of projects that benefit the most from using React, here are some of the best use cases for the framework:
• Social Media Applications. This type of application usually has an ever-evolving list of advanced features with sophisticated UI. React was initially built to work with Facebook, making it ideal for creating new social networking apps.
• eCommerce Applications. These apps consist of various APIs, complex filters, and other functions requiring a high degree of independence between components. Due to its inherent ability to build separate components that offer easy scalability, React helps developers implement all these features.
• Messaging Applications. The inherent abilities of React, along with useful WebSockets, help create a real-time instant messaging with a smooth user interface.
• Data Dashboards. React features like Isomorphic JavaScript, component reusability, and Virtual DOM allows it to create dashboard apps to pair with machine learning and business intelligence projects.

Reusability is key in reducing bugs and coding quickly. The more I use a piece of code, the more confident and familiar I become with it, which in turn significantly speeds up my development time. (Robert Duchnik, Web Developer)

Disadvantages of React. When to Avoid Using React?

Among the drawbacks and limitations of utilizing React are:

• In the initial stages of learning React, it can be difficult for developers to understand JSX concepts.
• Maintaining proper documentation is not easy as the React components can be updated quickly.
• Integrating React into a traditional MVC framework like Rail requires complex configuration.
• React is used to develop only the UI part of the app; other technologies are needed to get complete development tools.

React is used to handle the app’s view layer, and developers prefer this library to build reusable UI components. Many large-scale apps use React to load the data without refreshing the pages. However, this library requires the knowledge of JavaScript, and JSX can be pretty tough when it comes to learning. In case you don’t know JS or are a new developer, React may not be the best option for you.

Angular vs React. Tech side

Performance and DOM

Both Angular and React are excellent for web development, although there is a big difference between them. Angular operates on real DOM (Document Object Model), while React uses virtual DOM. Virtual DOM allows you to update the changes without rewriting the HTML doc virtually. It renders updates much faster and ensures fast performance regardless of the app’s size.

Testing

Code written in a dynamically typed language like JS has to come up with a robust set of tests. Angular has several features, such as a unit of code isolation and is written with all the testability concerns in mind. For example, the dependency injection Angular feature makes it easy to pass in dependencies of components and can also mock the components.

In React, tests are very predictable due to the availability of mocking functions. React offers test runners like Jest, Ava, and Mocha and executes test suites continuously to run the test cases as a part of the development process.

Data Binding

Data binding is related to synchronizing data between business logic and UI. Angular utilizes both one- and two-way data binding when changing data impact view, and changing view initiates changes in data. One/two-way binding increases the framework flexibility and is more straightforward to work with than one-way binding.

React uses one-way data binding when developers nest child components within higher-order parent components when designing a React-powered app. One-way binding makes debugging an app easier and makes the code more stable.

Bundle Size

The smaller the file is, the faster it loads. In its turn, the faster it loads, the higher the ranking and, ultimately, the conversion rate. Angular achieves this by not including development utilities and unused modules in the app, whereas React uses the webpack, dynamic imports, and tree shaking to reduce the bundle size.

Scalability

React lies heavily on third-party tools when you need to scale the app. However, a maintainable architecture with server-side rendering can be easily developed using this framework. At the same time, Angular comes with all the core features required for scaling an app by adding new functionality.

Key Differences Between Angular And React

Angular vs React. Which is Better?

Angular and React are excellent tools for web development and have much to offer in terms of features, performance, and tools, making it even more confusing for developers to choose between them. So, with all the pros and cons of these frameworks in mind, the final question arises - which is better: Angular or React?

Angular is a full-pledge framework for building mobile and desktop apps, whereas React is a JS library for creating complex interactive UIs. Compared to Angular, React has a shorter learning curve due to its simpler structure and small package size. For teams building an application out of a small learning curve, React is a go-to option. At the same time, when creating an enterprise-grade app with extensive development, Angular will fit best as a steeper learning curve is not a problem for these teams.

React is more popular - it constantly evolves and remains trendy. This framework has the simplest ways to reuse the UI components, offering an easy way to get the job done. React is better than Angular due to its rendering optimizations, virtual DOM, and easy migration between the versions. As for Angular, it can handle multiple things independently, so it may initially seem tricky. However, the benefits of this framework foresee the most extended concept and outweigh the time invested.

Choosing between Angular and React usually comes down to personal preference, as they both solve the same problems but in different ways. Both these frameworks are extremely powerful and represent a significant advancement over early web programming in improving, facilitating, and speeding up web development.
