React JS vs Angular Js – Detailed Comparison

React JS vs Angular Js, who is the better framework? Every developer has that question in his mind.Choosing the right framework for a new JavaScript system, application or website is a top priority for any business. It can have a direct bearing on project’s durability and ability to fit in deadlines, further code maintainability, and scalability of your future app.

JavaScript frameworks are developing at an extremely fast pace, meaning that today we have frequently updated versions of React js and Angular

Let’s go to see the battle ” React JS vs Angular Js “.

Advantages of angular js

  1. Developed By GOOGLE: AngularJS framework is maintained and developed by Google. Google takes care of every version of AngularJS.
  2. Global community support: Global community support is one of the factors, that can easily make Angular the best javascript framework. Developers and designers constantly collaborate and contribute to the community, increasing credibility and reliability of the framework.
  3. full-fledged framework: It is a full-fledged framework that can run in any browser or platform. Moreover, it is consistent, overwhelmed with ready-made tools, ng components are robust and quite mature, as contrasted with React.
  4. Angular-language-service — which allows intelligence and autocomplete inside of component external HTML template files.
  5. Unit Testing Ready: AngularJS framework is a unit testing ready framework that is its most compelling advantages.
  6. Two-way data bind: Two-way data bind is probably the top feature, as it diffuses the impact after every minor data change and does way with the need for further effort with data sync in view and model.
  7. TypeScript: Angular’s created to be used alongside with Typescript. And has exceptional support for it. TypeScript is an enhanced JS super-set that supplies optional static type checking, object-based programming patterns, and high-performance typing features.
  8. Component-based architecture: Owing to component-based architecture components have deep binding and each of them comprises elements with only relevant functionality. What is more, they are loosely coupled and properly encapsulated. Such approach makes components easily reusable, enhance their testability and further maintainability.
  9. Structure and architecture specifically created for great project scalability.

Drawbacks of Angular:

  1. Variety of different structures(Injectables, Components, Pipes, Modules etc.) makes it a bit harder to learn in comparison with React and Vue.js, which have an only “Component” in mind.
  2. Relatively slower performance, according to different benchmarks. On the other hand, it can be easily tackled by utilizing so-called “ChangeDetectionStrategy”, which helps to control the rendering process of components manually.
  3. steep learning curve and complexity: Despite a comprehensive and clear manual, steep learning curve and complexity are named among the main weak points of Angular.js. Like any other client-side rendering technology in javascript framework comparison list, programmers should place special emphasis on security to make apps reliable and safe. Though, with introduction of Angular Universal and pre-rendering option in ng2 this issue was defused.
  4. Confusion: with AngularJS there are many ways to do the same thing. Sometimes, it is be hard to find the right way for a task. Hence, it is essential for programmers to understand all components of it.
  5. Name Clashes: you don’t have the ability to formulate many ng-apps on the same page With Angular JS. This creates name clashes.

Advantages of Reactjs

  1. Easy to learn, thanks to its simple design, use of JSX (an HTML-like syntax) for templating, and highly detailed documentation.
  2. Great support for server-side rendering, making it a powerful framework for content-focused applications.
  3. JSX is a JS syntax that enables HTML quotes and usage of HTML tag syntax for subcomponents rendering. It promotes building of machine-readable code and provides ability to compound components in one compile-time verified file.
  4. Data-binding is one-way, meaning less unwanted side effects.
  5. Migrating between versions is generally very easy, with Facebook providing “codemods” to automate much of the process.
  6. Prompt rendering is among the best features of React that gives a significant edge over Angular. The technology comprises smart methods to mitigate the amount of DOM operations, optimize and accelerate the updates process. Virtual DOM (Document Object Model) is of great use while handling vast databases.
  7. Skills learned in React can be applied (often directly) to React Native development.
  8. The core difference between reactjs and angularjs is that React is JS-centric, while ng2 remains HTML-centric. JavaScript is far more robust, than HTML, that makes React far more simple, focused and consistent.

Drawbacks of React:

  1. React is unopinionated and leaves developers to make choices about the best way to develop. This can be tackled by strong project leadership and good processes.
  2. Comparing react vs angular performance, first of all it’s worth mentioning that reactJS is not a full-scale framework and for this very reason integration of the UI library into a common MVC framework requires deeper programming knowledge. It is still young and not mature, considering tutorial volumes, limited ecosystem, etc.
  3. The community is divided on the best way to write CSS in React, split between traditional stylesheets (CSS Modules) and CSS-in-JS (i.e. Emotion and Styled Components).
  4. React is moving away from class-based components, which may be a barrier for developers more comfortable with Object Oriented Programming (OOP).
  5. Mixing templating with logic (JSX) can be confusing for some developers at first.
  6. Apart from pros and cons of reactjs, we should also mention Flux that is frequently applied for adding a structure and architecture to react app. Usage of both technologies can become a challenge for non-experienced programmer, as it lacks structured and comprehensive documentation or guide.

Conclusion of ” React JS vs Angular Js ” battle

For a real engineer, there is no substantial difference in which framework to choose, because it just takes some time to get used to the new one. Every framework has its own pros and cons, meaning that there should be just the right choice for every single case during product development.

React and Angular offer completely diverse approaches to web application development for startup, small and medium businesses. Both are powerful and flexible technologies, while none of them is worse or better, than the other. Depending upon custom app goals and particular system constraints, developers can run from ng2 to React, and back.

Opting for Angular, it usually assumes the creation of core skeleton for a front-end app, whereas React.js can be applied to improve its specific parts. Moreover, it can be integrated with other frameworks, like Backbone or even well-known Angular.
