Most Popular Functions Of ReactJS and AngularJS

Quick Summary: In the vast and dynamic era of web development, it is natural to get confused while selecting the most appropriate JavaScript framework for frontend development. ReactJS and AngularJS functions both are the most popular selections for building sturdy and dynamic frontends. Developers depend on these frameworks for their immense capabilities and promise. By comprehending the core mechanisms of these two frameworks, developers can determine which one is optimal for their specific application requirements as the landscape of web development technologies continues to progress.

ReactJS: A declarative, component-based library 

The ReactJS programming framework, developed by Facebook, allows software engineers to build flexible user interfaces by assembling independent, reusable elements. With ReactJS, complex user interfaces can be deconstructed into separate, reusable parts called components. A few of the most commonly utilized functions in ReactJS include-

  1. Virtual DOM: Virtual DOM is similar to the clone of real DOM, which allows for the optimization in rendering and thus improve performance. Traditionally, when a component of a webpage or DOM was updated, the whole webpage rendered even with those parts that need no rendering, so this was a wastage of resources and time. But with virtual DOM, when the state of a component changes, React only modifies that part which needs to be updated, rather than updating the entire webpage.
  2. JSX: React uses a syntax extension for Javascript, which is JSX, to define the look and feel of components in a website. JSX allows developers to write HTML-like codes which makes it easier to create and modify UI elements. 
  3. Component based architecture: React utilizes a modular design where user interfaces are constructed from separate, self-contained components. These individual building blocks each encapsulate their functionality and presentation, facilitating the creation and upkeep of intricate front-end systems.
  4. State Management: WIth the built-in support of ReactJS, you can now manage the state of components efficiently through the use of hooks, which are basically functions that allows you to work with data and other features in functional components. 
  5. Reusable components: React code is highly versatile, allowing for seamless reuse within various sections of an app or even across distinct projects. This modular strategy simplifies the development process and enhances the manageability of code.

AngularJS, developed by Google in 2009, is an open source Javacript framework popular amongst developers for its capability to build dynamic websites and rich web applications. It is beyond the basic functionalities of HTML markup language as it is used to create and develop interactive web apps. AngularJS allows you to utilize HTML as a template, while providing features like data binding and code reuse. 

  • The increasing demand for responsive websites has grown over the years. And developers couldn’t trust on the basic HTML codes to meet this demand. 
  • They had to devise much more advanced techniques to create interactive web pages. As a result, they switched to Javascript code, jQuery, and AJAX. 
  • After the introduction of Javascript code on the client side, smooth communication between the website’s front and back end was made possible. 
  • And sooner, several web applications started following this strategy. However, it acted only as intermediaries between the presentation layer and the model. 
  • Javascript code failed in binding the data at the server end and user end. 
  • To eliminate these issues, AngularJS came into inception. 
  • AngularJS library removed the need of an intermediate component as it successfully coupled presentation data with end user.

AngularJS functions include- 

  1. Data binding- AngularJS functions include single and two-way data binding. You can manipulate data in the model layer and make updations in the view layer simultaneously. Automatic data synchronization allows data sharing and updating between both the MVC layers of the applications. And at the same time, it reduces the workload of developers as they no longer need to deal with separate layer codes. 
  2. Real-time testing- AngularJS offers both end-to-end and unit testing. Infact, the testing features in Angular framework maintain the premium code quality as codes remain bug-free. 
  3. Fast application prototyping- Developers can leverage AngularJS features to develop interactive apps by writing less codes. As a result, the production timeline is reduced from months to a few days, saving significant amounts of time, effort and resources. 
  4. Code reuse- It is a crucial feature for developers as it allows them to reuse the predefined templates and make changes in them as and when required. AngularJS library uses HTML templates, which can be used to develop interactive web applications even by those programmers who know bare minimum about coding. It saves their time and money while improving app performance at the same time. 
  5. Focus on UX- With evolution in web development, user experience has emerged as a crucial factor for all businesses looking to build trust and long-term relationships with their potential customers. AngularJS functions enable businesses to design and develop SPAs that allow customers to access all the information they require on a single page. 


Most popular framework

As evident from the graph, React tops in terms of searches noticed by Google Trends. Also, as per a Statista survey conducted in 2022, React has secured a second position in the list of “most used web frameworks” among developers worldwide. Angular is frequently chosen by programmers because it provides pre-built solutions and promotes good coding practices that result in clean, organized code.

Key differences and considerations

While both the frameworks ReactJS and AngularJS offer tools for building modern web applications, they have distinct approaches and mechanisms.

In selecting between these two options, arriving at your determination by weighing the positives and shortcomings of each is crucial. Our suggestion would be ReactJS, for the subsequent rationales:

  1. React is in high demand and employed in large enterprises.
  2. React, that is widely favored by programmers, is experiencing a surge in its already impressive popularity, as its daily downloads rise by around 9.6%.
  3. React offers features that make web development easier.
  4. Learning React is straightforward, and comprehending its structure is simple if you are earlier familiar with JavaScript.
  5. Many developers love using it.
  6. React allows for faster updates and both server-side and front-end support.
  7. Supports Android and iOS platforms.


Nevertheless, it is important to consider AngularJS to some extent; both frameworks are exceptional and were created to address specific issues. It is crucial to assess your project thoroughly. If your project requires adaptability, efficiency, and a streamlined approach, ReactJS may be the preferable choice. Conversely, if your project necessitates comprehensive functionalities such as integrated tools and enterprise-grade support, AngularJS would be a suitable option. To sum up, ReactJS and AngularJS are the top frameworks in a developer’s world, each offering unique benefits and features. By comprehending their characteristics and disparities, developers can make well-informed choices and harness the appropriate structure for constructing contemporary, adaptable web and mobile applications.
