How are ReactJs and AngularJs Different?


Every corporation, from startups to well-established corporations, likes to quickly develop trustworthy and strong web-based apps by utilizing a full-fledged, characteristic-rich framework.

The most widely used frameworks ever are still AngularJS or ReactJS if you're using Javascript to create an application. There are various aspects in which ReactJS & AngularJS appear as better alternatives for your front-end development projects, from user experience & performance to cost & compatibility.

Is the choice between Angular and React really a question of taste? In light of actual applications, this post provides a thorough comparison and analysis of various Angular and React components. Let's take a closer look to understand the key distinctions between both. Let us have a look at web development course fees too.

What is ReactJs?

You may create UI components using the JavaScript library called React, which was created by Facebook. React makes it easier to build interactive user interfaces. Moreover, React makes the code simpler to comprehend, run and compile. Using server-side rendering, the React Java Script framework offers a customizable, performance-focused solution.

What is AngularJs?

A structural framework for creating dynamic web apps is called Angular. It enables HTML to be used as a template language by developers and enables HTML's syntax to succinctly and precisely represent the components of the application.

It is a fully functional JavaScript framework that helps in creating dynamic, one-page web applications. Additionally, Angular supports the MVC programming model.

The History of ReactJS.

  • Jordan Walke built React in 2011 and made it open-sourced in May 2013.
  • React 16.0 was published by Facebook and Instagram in September 2017.
  • In September 2017, React 16 and React Fiber, the most recent version, were both published. The React Core Algorithm is continuously implemented in React Fiber.

The History of AngularJs.

  • Google launched AngularJS in 2010.
  • In September 2016, the Angular 2.0 version, sometimes known as Angular 2 or just Angular, was launched.
  • March 2017 saw the release of version 4.0.
  • In November 2017, version 5.0 was released.

Characteristics of ReactJs.

  • It enables the usage of third-party libraries.
  • React saves time and energy. 
  • Composability and simplicity.
  • Completely backed by Facebook.
  • Faster speed and improved user experience.
  • More rapid development.
  • One-way data binding for code stability.
  • Components for React.

Characteristics of AngularJs.

  • Built-in support for Observables, HTTP, and AJAX.
  • Extensive community backing.
  • According to technology.
  • Typescript is effective.
  • Crisper and cleaner coding.
  • Improved error handling support.
  • Angular CLI upgrades that are seamless.
  • Validation and forms.

Angular vs. React: Which is Better for Web Development?

Comparing React to Angular is like comparing apples and oranges. The other is a full-fledged framework, whereas the former is a library that deals with views. 

Naturally, the majority of React developers will extend React with a few libraries to make it a full-fledged framework. However, the comparison is still restricted because the final process produced by this stack is frequently still extremely different from Angular.

The main distinction is in state management. Data-binding is included into Angular. However, Redux is often added to React nowadays to allow unidirectional data flow and deal with immutable data. These are diametrically opposed strategies in and of themselves, and several debates are now taking place on the merits of mutable and data binding vs immutable and unidirectional.

Data Binding

Undoubtedly, data binding is simpler to use initially than the unidirectional method. Of course, it's also feasible to take an entirely different approach and combine Angular and Redux with React and mobx-state-tree, respectively. 

Digital Properties

Plain getters in Angular are just out of the question in terms of speed because they are called on every render. Use of BehaviorSubject from RsJS, which completes the task, is feasible.

Use @computed from MobX with React to accomplish the same goal with what is probably a somewhat prettier API.


Instead of having a single large global router configuration, component-based routing enables components to control their own sub-routes. In version 4, react-router has at long last adopted this strategy.

Useful Design

It's usually ideal to start with some higher-level components, and material design has practically become the standard pick across all projects, including those that aren't Google-related.

I purposefully picked React Toolbox over the frequently suggested Material UI since Material UI has significant, openly acknowledged performance issues with their inline-CSS approach, which they want to address in the following release.

Additionally, Sass/LESS are starting to be replaced with PostCSS/cssnext, which is utilized in the React Toolbox.

Detailed CSS

CSS classes resemble global variables in several ways. A clear current trend is employing libraries that assist process CSS to prevent conflicts rather than requiring a front-end developer to come up with complex CSS naming schemes. There are several ways to organize CSS to prevent conflicts (including BEM).

Project Architect

It is somewhat more practical to have a CLI generator for a project rather than needing to clone boilerplates from GitHub.

Validation of Forms

Form validations are a complex and often utilized feature. To avoid code duplication and problems, it's a good idea to have things handled by a library.

Bundle Size

AOT compilation in Angular and Tree Shaking in React are two examples of the application generators' default settings for the production minified JS bundle sizes.

Angular Js:1200 KB

React Js: 300 KB

The more substantial one has always been angular. The sizes are reduced to 275kb and 127kb, respectively, when using gzip. Remember that this is essentially the entirety of vendor libraries. In contrast, there is very little actual application code, which is not the case in a real-world program. There, the ratio would likely be closer to 1:2 than to 1:4. The bundle size also has a tendency to increase pretty rapidly when you start using a lot of third-party libraries with React.

Flexibility of Libraries vs. Robustness of Framework

It turns out that, depending on the frameworks we decided to use React with, the development procedures in React and Angular might be extremely similar. So, the decision ultimately comes down to choice.

  • Choose Angular if you want ready-made stacks, robust dependency injection, and intend to leverage some RxJS niceties.
  • Choose React/MobX if you like to experiment and develop your own stack, if you appreciate JSX's simplicity and prefer simpler computable properties.
