Technology has divergent forms to serve its users in different ways with each passing year. When we talk about the most popular Frameworks of frontend to create excellent web applications, there is ample choice in the market. But, when we specifically look at the features and merits of any Framework, there are two most well-known Frameworks among some new and old ones; Angular and React.

Herein, we will take you to the road of a complete and comprehensive guide on Angular VS React; that shall clear your ifs and buts about these both with a final remark telling you which one should be for your dream project. Let us dive into the article without further ado.

What is Angular?

The Web Framework known as Angular was first introduced in 2010 as AngularJS and is now developed and maintained by Google. It rose to prominence among web Frameworks somewhere at the time and did so swiftly. This was made possible by features like dependency injection and two-way data binding, in addition to the fact that a tech juggernaut supported it.

As a complete redesign of AngularJS or Angular 1.0, which was first launched in 2010, Angular (also known as Angular 2.0) was introduced in September 2016.

  • Speed and performance is an important feature that serves the application process in a better way.
  • Cross-platform functionality that makes your work easy on any device.
  • Best at productivity with simple and beautiful templates.
  • CLI enhancement.

What is React JS?

React, is a Javascript Library launched by Facebook, to build intuitive UI elements in 2013. This popular Framework went into the favorite list of the developers for its nicely built components that help them to create minimalistic designs based on various qualities such as

  • The components are easy to use and handy modular to enhance the functionality timings with multiple usages.
  • The logical section of any app is easy to use by the developers by just changing its view since it is used in mobile applications.
  • Self-composed modules or components are quite simple to use and maintain.
  • Easier coding to understand.

React took the whole market in one swap with its tremendous features, leaving all Frameworks behind including Angular. And to this overwhelming response from the users, Google had to improve its Javascript Framework in the year 2016 with the name Angular2. Isn’t it enough to tell about the fame of a Framework, holding the passion of the users for it?

Angular and React: Core Concepts

Both Frameworks have different approaches and concepts to working on variability scales. Let’s know each of them one by one.


Learning Graph
Any Framework’s learning curve takes into account more than just how simple coding is. The simplicity of testing and debugging is also taken into account. For projects that require a large amount of coding, this is of utmost importance.

Angular has a more difficult learning curve than React. You must become familiar with fundamental ideas like directives, modules, decorators, functions, and templates. After mastering these fundamentals, you must move on to more complex ideas like AoT compilation and Rx.Js.

Models, Controllers, and Views, make up the three levels that make up the Angular Framework. It has a fixed, intricate structure. With Angular, the developers may reuse the templates and codes more easily because they divide them down into distinct files.

A feature module is one of the core concepts of Angular as well as a good practice for providing integrated functionality based on a specific application according to the needs of the users such as forms, routine, workflow, etc. Remember; the root modules are also enough to help you in your application but the featured module is helpful in the partition of any specific application core or area.

Template in the term of Angular, is a design for a UI element. To modify HTML components before their appearance, it is important to use the Angular template as they merge the Angular makeup with HTML. This HTML template indicates a view or interface of the application on the browser with the maximum functionality integrated.

Speed and productivity of the development process
The Angular Framework’s CLI offers an excellent development environment. With only a few code lines, it generates an excellent workspace and enables quick component design. There are numerous built-in methods that can easily resolve your issues.

After Angular 2, Angular 4 is backward compatible. One disadvantage of Angular as a JS Framework is that versions below Angular 2 are not compatible with backward compatibility. All the versions after Angular 2 support NodJS 6 and later versions and typescript 2.0 or later. A minimum storage of 10 GB and a minimum RAM of 4 GB are required to run Angular Applications.


Learning Graph
You need to become familiar with using JSX before using React. Additionally, you must be skilled at creating components, controlling internal states, and configuring properties. Because React doesn’t have a routing library, you also need to understand how to develop routing libraries. Additionally, you must be knowledgeable about interprocess communication libraries like Redux or MobX.

There isn’t a set format for writing programs in the React library. The React library was used to write understandable, well-structured code. The code can be rationally organized thanks to the use of component trees. Functional programming is another feature of the Framework, making the component definitions declarative.

Props and States
Props or properties are the objects that passed to React components from their origin component, so we can call Prop a child component. Props are the arguments that are offered for the function whereas, react components stand for functions. Now, coming to the state. It is a value that the React component starts by itself and it could be changed anytime during the component lifecycle.

Life cycle hooks
React state and lifecycle aspects can be “hooked onto” from function component code via hooks. Hooks allow you to use React directly without classes- they do not need to work inside the classes. Moreover, React has a few pre-set hooks to use.

Speed and Productivity of the development process
The pace and productivity of React development are impacted by the usage of third-party libraries. React has a variety of tools. When an app is delivered to a developer for an upgrade, more time must be spent because the tools used vary depending on the project.

React 16 even has support for deferred rendering and is fully backward compatible with earlier iterations. Along with GraphQL and Jest, it is likewise entirely open-source and released under the MIT license.

Technical Criteria


Real DOM is used by Angular in its apps. Real DOM is ideal for single pages that are occasionally changed. Additionally, the large library size slows down Angular-based apps. For instance, UpWork is among the most well-known apps that use Angular because there is less requirement for the user feed to be updated frequently.

Every six months, Angular releases one significant update and offers a six-month depreciation window for each version. The whole Framework comes with different bundled products, and updating is rather simple.

Data Binding
The Angular Framework employs a two-way binding strategy, which instantly updates the model state if a UI element is changed and vice versa.

DOM (Document Object Model)
An essential indicator in assessing any Framework’s effectiveness is Document Object Management (DOM). The DOM arranges the HTML and XML documents in the shape of a tree, as we have already explained.

Because Angular apps use their mechanism, every time a single update is made, the entire tree structure is refreshed. This slows down the procedure.

React offers more flexibility than Angular provides. Only other Frameworks may use Angular components, and the corresponding codes must be placed within an HTML application. Apps that need near real-time changes to be seen are hampered by this rigidity.

Accessibility to developer
The learning curve for Angular is steeper than for other Frameworks, and it uses a lot of extraneous syntax for tasks that don’t require it. As a result, project delivery times are longer and coding time is increased.


Some Developers integrate Application State management libraries to handle the challenges while using the React hooks. State Management is a platform that helps in generating communication and sharing the data component. The library is also compact, which makes it lighter and more lively. For instance, Instagram makes use of React because it demands frequent updates to the user feed.

React-based scripts can simply switch from using older to newer APIs. As we can see from Facebook’s interface, the APIs are rather reliable. Compared to Angular, updates are seamless, and migration is relatively simple. The major releases provide quick-changing libraries while staying neutral and stable.

Data Binding
One-way communication is used by the React library. This method only permits changing the UI elements after changing the component’s state. Although the two-way method appears to be simpler, React’s one-way method is more efficient for projects requiring a lot of writing.

DOM (Document Object Model)
Because React employs a Virtual DOM, developers can modify any node of the tree without having to modify the entire tree. A virtual DOM just changes the elements rather than updating the node elements. Whereas the real DOM will modify the new elements that are changed in real.

Developers working with React have access to a wide range of tools, Frameworks, and architectural options. A talented React team can choose the technologies they require from the outset and produce a highly personalized product.

Accessibility to developer
Compared to Angular, React requires more setup time but enables beginners and professionals to build apps rather quickly. React, unlike Angular, allows you to add new functionality using a variety of libraries. Like Angular, React requires model and controller components.

Maintenance & Version History


Angular is a TypeScript-based open-source JavaScript Framework. It was created and is supported by Google, and it works with a variety of code editors. Angular must be used in the front-end creation of interactive web apps and websites.

The second version of “Angular,” which was released in 2016, was a complete rewriting of AngularJS. One of Google’s most significant initiatives, Google AdWords, makes use of Angular.

The version of Angular is updated every 6 months majorly. To get the insights, you can visit the link here.
