What is React JS?
React JS (also known as React) is an open-source JavaScript library used to create user interfaces (UI) for web applications. It was created by Facebook in 2013 and quickly spread throughout the world of web development due to its innovative approach to creating user interfaces.
The unique feature of React is that it allows the creation of reusable components for the user interface, which are then interconnected to form the complete interface. Another key aspect of React is the use of Virtual DOM, a virtual version of the DOM (Document Object Model) tree. It allows for faster and more efficient page updates, thanks to faster detection of changes than a traditional DOM.
React also uses a markup language called JSX for creating components, which can be considered a fusion of HTML and JavaScript. React handles the client-side user interface logic, interacting with data via a server or API and rendering the page in the browser.
In short, React is a JavaScript library that enables the creation of dynamic, fast, and scalable user interfaces using a set of reusable components and a Virtual DOM.
What is Angular JS?
Angular JS ( also known as Angular version 1.x) is an open-source JavaScript framework developed by Google for the rapid and efficient creation of dynamic, multi-page web applications. It was launched in 2010 and has remained one of the most popular technologies in the world of web development, although its most recent version (Angular 2 and above) has incorporated major changes.
AngularJS uses the MVC (Model-View-Controller) design pattern to separate data presentation from business logic. This allows for greater organization and scalability of applications, making them easier to understand and maintain.
Another key feature of Angular JS is data binding, which automatically synchronizes data between the view and the model so that any changes made to one are immediately reflected in the other. This feature is particularly useful for creating interactive forms, for example.
Angular JS also offers numerous built-in features for form validation, error handling, creating animations and special effects, and building complex dynamic web applications.
In short, Angular JS is a comprehensive JavaScript framework for developing dynamic web applications, which uses the MVC model and data binding for efficient organization and management of data and business logic.
Who uses React?
According to the 2018 State of the Developer Ecosystem Survey, React is used by 60% of developers worldwide. Similarly, Facebook has one of the largest active user bases in the world, as it uses React for the platform's mobile applications.
The main companies that use React are as follows:
- Netflix
- Yahoo
- New York Times
- Discord
- Dropbox
- Uber Eats
- Atlassian
Who uses Angular JS?
Today, Angular JS is used by more than 500 large companies around the world. Angular JS is definitely at the top of the popularity list. Due to its diversity, everyone from the software industry to the gaming industry can rely on the framework.
The main companies that use Angular are as follows:
- Microsoft
- IBM
- PayPal
- Upwork
- Deutsche Bank
- Samsung
- Forbes
- The Guardian
- Rockstar Games
What are the advantages of using React JS?
- First, it is a very flexible and powerful platform, thanks to its own virtual DOM to which your components can attach. The advantage is that React JS will calculate all the changes required by the DOM and directly update the part that needs it.
- The technology facilitates the creation of user interfaces and reusable components, and data can be modified at any time.
- The toolkit provided by React JS is also a very important advantage. Because it is comprehensive and optimized, it allows you to easily initialize a project without defining its schema.
- What sets it apart from other frameworks is that the service content is searchable. With the use of a Node server, code can be generated on both the client and server sides.
- A large and active community has formed and can help you design your digital project. It lists all the bugs and anomalies you may encounter.
- If you already have a web application with React JS as the front-end, it will be easier to support it with React Native.
- Typically, for any technology migration, you need to keep up with these developments by managing updates to avoid bugs. With React JS, you can continue to use the features of the new version without having to modify all your code.
What are the disadvantages of React JS?
- This is just a view layer; you still need to hook up your code for Ajax requests, events, etc.
- The library itself is quite large.
- The learning curve can be slow.
What are the advantages of using Angular JS for your project?
- It is a powerful and easy-to-adopt framework for web developers because it is written in the well-known JavaScript programming language.
- It is also considered flexible.
- It requires a highly structured component-based architecture and demands that data exchange between components be easier to understand. Its goal is to encourage generic implementation, like a "framework agnostic," which will allow Angular code to be reused in different contexts.
- The framework provides everything you need to develop a complete application with a standard configuration, such as animation modules, optimized build configuration, form modules, etc.
- Testability is very important. To this end, it provides all the necessary tools to facilitate the implementation of unit tests.
- Angular is also well known in the world of mobile development. Ionic, which is an open-source framework for cross-platform mobile applications, uses it.
- A large community of expert developers.
The disadvantages of Angular
- It has different structures such as components, pipes, injectables, and complex syntax, which makes it difficult for new developers to learn.
- It is less powerful than other frameworks (React and Vue).
Here is a comparative table highlighting the advantages and disadvantages of each technology.
React JS | Angular JS |
JavaScript library for creating dynamic user interfaces | MVC framework for creating SPA web applications |
Focuses on building reusable components | Use data binding to synchronize views and models |
Virtual DOM for faster and more efficient page updates | Involves a steeper learning curve due to its comprehensive feature set |
Enables dynamic elements on a web page using concepts such as JSX | Includes a wide range of built-in features for form validation and animation creation |
Large open source community for package and library development | Updates can render existing applications obsolete. |
Easy integration with third-party libraries | Requires a higher level of complexity for larger projects |
Ideal for small and medium-sized projects | Mainly suitable for large and complex projects |
Conclusion
Ultimately, the choice between React and AngularJS depends on the specific needs and requirements of the development project. If a project requires a large number of built-in features for creating large-scale web applications, AngularJS may be the ideal choice. However, if the project is small or medium-sized and requires dynamic elements on the page, React may be the best option.
