Some AngularJS establishments include Google (Google Express, Analytics, Firebase Console, etc.), Forbes, NBA, Wix.com, and Onefootball.
Features and Advantages of AngularJS
- AngularJS is a full-fledged framework that can run on any browser or platform.
- The framework helps extend the HTML vocabulary to suit the dynamic nature of your applications using Angular elements.
- AngularJS has rich features and offers a fully extensible tool set. This makes it possible for developers to rapidly build and deploy visually attractive, single-page, and real-time applications.
- One of the top features of the framework is that it offers two-way data binding. This distributes the impact every time there is a change in data. It also means there is no need to write extra code for data synchronization in view or model components, as AngularJS will automatically perform this.
- Due to the framework’s architecture, the components are deep-bound. These components consist of elements with only relevant functionality. They are also loosely coupled and adequately encapsulated. Hence, the components are easily reusable.
- AngularJS is testing ready for both Unit testing and Integration testing. The designers developed a “Karma” testing framework for this purpose.
- The framework has rich community support across the globe. Developers and designers constantly collaborate to keep improving the framework.
Disadvantages of AngularJS
- One primary limitation of AngularJS is its complexity and steep learning curve despite a comprehensive manual and documentation.
- Until recently, programmers using this framework had to emphasize security to make the applications safe and reliable, similar to other client-rendering technologies in the list of JS frameworks. This limitation has now been defused by the introduction of Angular Universal and the pre-rendering option in ng2.
React JS is more of an open-source JS-based library than a framework developed by the Facebook community. It takes a minimalist approach to building web applications. Yet, it offers excellent functionality and scalability, providing a responsive, intuitive & attractive UI. The framework also has the ability to handle large and highly dynamic data. Some companies that use ReactJS include Facebook, Instagram, WhatsApp, Netflix, and AirBnB.
Features and advantages of ReactJS
- One of the best features of ReactJS is its prompt rendering, which is an advantage over AngularJS. This is because of the well-defined functional components that explicitly map the input props and the delivered output.
- Functional components also allow the code to be reused and tested quickly.
- The framework comprises a virtual DOM (Document Object Model), which reduces the amount of operations done on the primary DOM. The framework also uses innovative methods to optimize and speeds up the DOM update process.
- ReactJS uses JSX, an XML-like markup language that enables the usage of HTML tags for subcomponent rendering. Static analysis is the major advantage provided by JSX. If you make a mistake in your JSX markup, the compiler will throw an error, which helps you catch typos and errors immediately.
- ReactJS has one-way data binding, which makes it more performant than Angular. One-way data binding also makes it easier to debug a ReactJS application than an AngularJS application.
Disadvantages of ReactJS
- Compared to AngularJS, ReactJS is not a framework but a front-end library. Integrating this library into the MVC architecture needs a deep understanding of programming.
- Though ReactJS is older than Angular, it is not a completely mature framework considering the aspects such as its limited ecosystem and tutorial volumes.
- Another major drawback of ReactJS is that the environment constantly changes quickly, and many developers find it challenging to keep up with the pace of these changes.
- While JSX has its benefits, many developers in the community believe it to be a disadvantage. There are a lot of complaints about its complexity and steep learning curve.
- Functional components, too, have their own limitations. For example, unlike class components, they cannot have a state. This means developers must keep switching between these two paradigms to exploit them fully.
