Angular vs React: Who Rules the Smart Web?

You must have come across the term “Smart Web” quite often. “Smart Web” stands for the platform agnostic web application that is resourceful and gives the user a feel for a singular app. On the contrary, the conventional web applications are, usually, a collection of pages. Angular and React are the two examples of most popular technology for building Smart Web. Angular, one of the most popular JavaScript frameworks, offers multiple innovative and out-of-the-box solutions. React, on the other hand, uses a number of components (JSX) and React core acts as one skeleton where those components fit. Hence these every piece of these components put together makes a whole application. Both Angular and React have been recognized and used by big companies across the world. Google moved a majority of its UI to Angular JS before 2011 for its “Single Page Application” (SPA). On the other hand, Facebook introduced the concept of Virtual DOM to overcome client script bottlenecks using React. React laid the overall foundation of Facebook’s web UI, one of the easiest and most popular user interface. However, today, both the user interfaces are market leaders and their comparison is inevitable.


Angular, released in 2009, has evolved over time with semi-regular releases. The latest 1.x version of Angular is 1.3.8. Alongside, Angular also released its 2.0 version. The current Angular 1.x version uses custom HTML elements with attributes that provide functionality on various DOM (Document Object Model) elements. These DOM elements are also called directives and are versatile in nature. As far as embracing typescripts is concerned, Angular 2.0 counts on HTML templates. Both versions support MVC (Model-View-Controller) architecture to overcome complexity and deliver ease in development. However, Angular 2.0 is still struggling to gain popularity as compared to Angular 1.x even though Stack Overflow reports more queries in Angular 1.0 than in 2.0.

Facebook developed React, a performance-intensive script. Many MVVM (Model–View–View-Model) frameworks face a hard time rendering large amounts of data. However, React overcomes this difficulty, as it renders the changes only with the help of the Virtual DOM. Facebook invented the terminology “virtual DOM” for increased performance by writing out a full render virtually, checking the difference between the virtual render and what’s on the DOM and then creating a patch. Moreover, React uses plain JavaScript and JSX to write views, which means that JavaScript and HTML can be used in the same file. However, it is not necessary to use JSX to write React views, but it is suggested as it simplifies the process.

Advantages of Angular

1. Global community support

One of the determining factors, that can crown Angular as a better JavaScript framework is its worldwide recognition. Developers and designers constantly collaborate and contribute to the community. Thereby, increasing the credibility, reliability, and usability of the framework.

2. Full-fledged framework

Angular is compatible with all platforms and browsers. It is consistent, has inbuilt tools and robust components. Moreover, it is quite mature and developed as compared to React.

3. Two-way data bind 

Two-way data bind, a key feature of Angular, diffuses the impact of minor data change and decreases the need for further effort with data sync view and model. The change of data in the client side does not need to make a server call. The UI with help of the model are updated real time. That too without writing a single line of client script.

Advantages of React

1. JSX

JS syntax or JSX enables HTML quotes and uses HTML tag syntax for subcomponent rendering. This leads to the building of machine-readable code and imparts capability to compound components in one, time-verified file.

2. Prompt rendering

This is one of the best features of React that gives it a significant edge over Angular. The technology comprises of smart methods to reduce DOM operations and eventually optimize and accelerate the update process. Additionally, Virtual DOM aids Angular to handle vast databases.

3. JS centric

The core difference between Angular and React is that React is JS-centric, while Angular still is HTML-centric. JavaScript is way more robust than HTML, which makes React simpler, more focused and consistent.

4. Mobil App Development

In case of Mobile App development, React uses React Native to develop the application.

Disadvantages of Angular

The high cost of developmentsteep learning curve and complexity are primary weak points of Angular. 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. However, the introduction of Angular Universal and pre-rendering option in ng2 helped defuse this issue. Even though it is a successor of one of the most popular tools for smart web development, Angular 2.0 has failed to live up to the expectations.

In case of Mobile App development, Angular doesn’t build the application on its own. It rather outsources it to platforms such as Ionic Framework.

Disadvantages of React

React is not a full-scale framework considering performance and usage. For this very reason, the integration of UI library into a common MVC framework requires deeper programming knowledge. It is still young, considering tutorial volumes, limited ecosystem and manageability issues with components. Further development of React is facing timeline issues.

Flux is an extension that is frequently applied for adding a structure and architecture to react app. Usage of both technologies can become a challenge for a non-experienced programmer, as it lacks structure, guidance, and comprehensive documentation.

Smart web is evenly divided between these key players. Others Javascript like AmberJS and KnockOut are slowly gaining popularity. Nevertheless, Bexcode Services suggests that if you have a complex structured application, React is your way out. Angular is more suitable for thorough development life cycles.
