Web development

The most popular JavaScript frameworks used by front-end developers these days are AngularJS and ReactJS. In addition, these two, together with Node.js, make it the top three most commonly used frameworks.

Both Angular and React are similar in popularity, in architecture, and are based on JavaScript. So what's the difference? Which of these is better? Here we start by looking at their general characteristics.

Angular vs React - an overview

Angular is a front-end framework by Google and is a type-based JavaScript framework. It contains in-built support for components like MongoDB (a NoSQL database), Express.JS, and a web application framework, AngularJS - a front-end framework and Node.js which is a server platform. Angular is also part of the MEAN stack and code is compatible with a large number of editors and it is considered the ideal option for dynamic websites and web apps. Angular 2 (and the original name - a monolithic change occurred when leaving "JS" from AngularJS) Angular 2+ is called Angular only. While AngularJS (the first version) still receives updates. The latest version of Angular is the Angular 7 was introduced in October 2018.

Meanwhile, React is an open source JavaScript library that was created in 2010 to create a dynamic user interface. It is based on JavaScript and JSX - a PHP extension introduced by Facebook that allows for the creation of reusable HTML elements for front-end development. Current stable version 16.X was released in November 2018.

Common factors in React and Angular

Component-based architecture

There is a component-based architecture in both angular and rectangular structures. In simple words, this means that in an app there are modular, consistent, and reusable components that are amalgamated to create user interfaces. Component-based architecture is maintained more in comparison to other architectures used in web development. This factor speeds development by creating different components that allow developers to rapidly adjust and scale the app.

App size and performance

AngularJS was previously known for its low performance during handling dynamic, complex applications. Meanwhile, due to the ReactJS App-Virtual Dome of the same size, AngularJS performs better.

Since the introduction of new versions of Angular, its features and elements such as eg The Shadow API have made the competition between frameworks. Apart from this, according to Jacek Schae's research from, it also states that the new versions of Angular are slightly faster than React and Redx - where the angle of Angular compared to the angle with the residual (in refracted research) The size is small. 129 KB, while React + Redux is 193 KB.

Angular vs React JS - Framework vs Library

React is not a framework, it is a library. This requires many integrations and additional equipment and libraries. Meanwhile, in Angular, you already have everything when you start developing an app.

Angular RxJS is included - it is a library for asynchronous development which reduces resource consumption by setting several channels of data exchange. It allows management of individual events simultaneously. However, the problem is that when RxJS can work with many configurations, you have to use angular to learn from the library.

Other features include dependency injection, Ivy renderer (new angular rendering engine), angular CLI (powerful command-line interface), angular universal (a tool for server-side rendering), code editor (Aptana, WebStorm, subdivision text, visual studio Code included.).

On the other hand, React requires many integrations and support devices to perform.

Redux is a state container that prompts the reactants to work in large applications; It also manages components in applications with many dynamic elements and is also used for rendering.

The React Toolset includes Babylon (trans-compiler modifying JSX in Javascript), React Router (URL routing library), WebPack (Standard Code Bundler), Code Editor (Atom, Visual Studio Code, Sublet text). Different tools like testing and debugging zest (for JavaScript code), enzyme and unexpected-feedback (component testing), React-unit and React-Testing libraries, skin-deep (render test) in the React uses utensils etc.

DOM - Real vs Virtual

Angular uses Real Dom. In this case, even if only one section of the tree has been changed or modified, the data structure of the entire tree has been updated. Using Real Dom, Angle finds that which components need to be changed to detect change.

React JS uses Virtual Dome which allows developers to track and update changes without affecting other elements of the tree.

While the Virtual Dome Real Dome is considered to be faster than joint-breaking, the current implementation of detecting changes in angular makes both approaches comparable to speed and performance.

Data Binding - Two way vs Downward

Angular uses two-way data binding which is similar to MVC architecture - where the model and visual sync are being engaged so modifying the data affects the view, which results in a change in the data. This approach guarantees that when a change is done in the UI element, and on the contrary, the model position is automatically modified.

In the meantime, React One-Way or Downward uses data binding. This type of binding does not allow hair elements to affect the basic elements when updated. This ensures that only approved components have been changed.

The downward data binding style makes the code more stable; however, additional work is also required to synchronize the model and view for it. Also, it takes longer to configure updates in the basic components indicated by changes in the child's components.

One-way binding can make the code more stable and debugging easier, but working with traditional two-way bikers is easy.

Growth speed and productivity

Angular provides a better development experience due to its CLI, which enables the development of workspace and design work applications faster; Building components and services with one-line commands, solving clean coding features of wide and type-scripts in in-built process.

In the meantime, due to the involvement of third-party libraries, the speed and productivity of React affect. Thus, React.JS developers have to determine the right architecture along with the tools as well.

Mobile app development & portability

The Angular framework is for the appeal of Angular mobile application development and UI component library. Thus, the last app looks like a web in any original web app container on any device.

Meanwhile, the React JavaScript library actually provides the basic UI experience that allows you to build your components and bind them to the original code written in Cotlin, Java, and Objective-C.

When it comes to tools to port existing web applications to mobile apps - both frameworks provide good alternatives. Comes with Angular Native Script, a cross-platform mobile framework that uses typescripts and allows 90% code in iOS and Android, ports business logic and when working with the UI, the same skill set Uses. NativeView approach is to write a UI for mobile and modify it to accommodate each platform when needed.

Meanwhile, ReactJS which comes with ReactJS is a JavaScript framework that is a cross-platform implementation for mobile applications that also allows portability from the Web. The attitude of the Reactive Native is such that the community is encouraged to write the various yarns for different platforms and to follow the mantra of 'learning everywhere and writing everywhere'. Consequently, the estimation of code sharing is approximately 70%.

Angular vs React popularity

Since both 'React' and 'Angular' are both common terms, it is difficult to understand their popularity through Google trends. A good option for understanding the popularity of both the framework is through the number of stars that meet their GitHub repository.

When to use React or Angular?

When you experience angular developers in previous versions of C #, Java and angular, then choosing an angular framework is the best option. If you want to develop the application solution, there is a complexity which is low to a moderate level, large scale feature is required and high productivity is required, angular is the right choice.

In the meantime, feedback is the right choice for you if your team is well-versed in CSS, HTML, and JavaScript. If the app you need to develop is a highly-customized specific solution and requires different components of diverse, convertible states (enable/disable buttons, user login/access permissions, or 300active/inactive navigation items), Then React is best for such development solution.


The Angular framework is more mature, well supported in terms of contributors and provides powerful support and tool-sets to support overall front-end development. Continual updates and support from Google suggest that the framework is not going anywhere and Google is trying to protect the current community and switch them from AngularJS to Angular 2+ with high performance.

Meanwhile, React is old enough and there is a large number of contributions from the community. It suggests a lightweight approach to developers that they start quickly without learning more work. At present, they react in the case of Angular's performance is similar.
