Angular vs. React: Which Is the Best Choice in 2024?

Libraries and frameworks are irreplaceable assistants for software engineers. They take on some of the developers’ tasks, facilitating the creation of apps and websites. The leading JavaScript frameworks for frontend projects today are React.js and Angular. We’ve compiled comprehensive overviews of these two tools, with their advantages, disadvantages and peculiarities, to help you decide which one is better suited for your project demands.

What Is Angular?

Angular vs React

The history of Angular dates back to 2010, when Google released AngularJS — an open-source framework written in JavaScript and aimed at creating single-page applications. It offered a set of components and MVC and MVVM architectures needed for building user interfaces for such apps.

In 2016, however, the Angular team totally rewrote AngularJS and released the Angular version 2.0 (or just Angular). The framework is also open-source, but its basis is TypeScript. With all the refinements, the goal of Angular is to develop dynamic and scalable web applications, which means more business opportunities for small companies and large enterprises.

Since the beginning of 2022, Google provides no support for AngularJS in terms of security or compatibility issues. At the same time, November 2021 saw the release of the Angular 13 version, and the development team promises to deliver upgrades twice a year. Therefore, Angular remains a development platform that can be taken into consideration for new projects.

Angular is a well-structured framework based on directives and components. The recent Angular versions are cross-browser compatible, i.e., they automatically load polyfill scripts, so that the JavaScript code is appropriate for each browser, including Firefox, Chrome, Safari, Edge, iOS and Android. A wide suite of libraries and tools within the framework allows developers to create enterprise-grade solutions.

What Is React?

React vs Angular

React (or ReactJS) is a JavaScript library used to develop user interfaces for web and mobile applications. The initial library release occurred in 2013. In April 2022, React version 18 was born. Additionally, in 2015, the React Native framework for developing native mobile applications was created.

All the ReactJS technologies are released and supported by Meta (formerly Facebook). Since they are open-source, a worldwide community of enthusiasts contributes to their advancement. Frontend development with React.js results in fast, interactive and scalable apps compatible with all platforms.

SaM Solutions’ React team offers a wide range of React services, including consulting, migration, web React development, and mobile development with React Native.

Features of React and Angular

The two frontend frameworks, React.js and Angular (though React is a library, it is often referred to as a framework), are highly popular among developers and business owners. Let’s take a look at the features of both technologies that make them so efficient and appealing.

Angular Features

Components — the basic building blocks of applications. An Angular-based app is a tree of components. Angular components are TypeScript classes with decorators above them. They help you define what metadata Angular calls, including the template, styles, selectors, etc.

MVVM architecture — the Model-View-View-Model design pattern in Angular is used to divide the application into three functional parts. This separation streamlines development and ensures software maintainability because one component can easily be changed without affecting the code of another component.

Two-way data binding — the mechanism of data synchronization between the model and the view. This means that if the model is changed, the change is automatically and instantly reflected in the view and vice versa. This approach guarantees that the model and the view are always updated.

Dependency injection — a composition of structural design patterns in which one object (service) is responsible for each application function. An object (service) may need to use other objects (dependencies). Dependencies are injected into the service at the time of its creation.

Angular Command Line Interface (CLI) — an official tool for initializing and working with Angular-based projects. With simple commands, it saves you the trouble of complicated configurations and build tools such as Webpack. CLI also enables end-to-end application testing.

Declarative UI — the usage of HTML instead of JavaScript to describe the interface layout, which is quicker and easier.

React Features

Virtual DOM — a virtual representation of objects from the real DOM that makes the code updates faster and memory-efficient. The essence of this virtualization is that any changes in the code are first reflected in this virtual copy, and the real DOM updates only pieces of code where modifications took place, instead of updating the entire UI project.

Components — ready-made code units with their own controls and logic. They serve as building elements of ReactJS apps and can be reused within a project, making the development highly convenient and quick. This is an especially useful feature for large-scale projects.

Declarative paradigm — you just need to describe the desired result, i.e., how parts of the application interface look in different states. React will update them in a timely manner when the data changes. Thus, you declare various components: a functional component is declared with a certain function; a class-based component is declared with a certain class. Declarative views make the code more predictable and easier to debug.

One-way data binding — the feature for synchronizing data between the app state and the view. With one-way data binding, the data flows in one direction, from parent to child components. Properties are encapsulated and are not available to other components. This feature ensures the improved control of code quality because developers can’t modify component properties directly.

JSX — a syntax extension for JavaScript similar to HTML. It allows developers to easily structure component rendering because they’re familiar with the syntax.

React Native — a framework with native mobile components, allowing you to make the React code compatible with mobile platforms (Android and iOS) and develop native mobile apps.

Advantages of React and Angular

Each tool has strengths and weaknesses that you need to consider when choosing a tech stack for your project. Let’s discuss the key benefits of React.js and Angular.

Angular Advantages

  • Cross-platform development — Angular allows you to build solutions for web, desktop and native mobile platforms (with NativeScript or Ionic).
  • App speed — the complexity of modern JavaScript apps may reduce their loading speed. In Angular-based applications, you don’t need to compromise the speed or features thanks to code splitting. Component Router automatically divides the JavaScript code into chunks and loads only those pieces the program needs to render the view requested by the user.
  • Built-in testing — Jasmine and Karma testing frameworks come by default with Angular CLI. When a component is created, they automatically generate basic unit tests and show results on a web page.
  • Productivity — Angular offers tools such as templates and CLI that streamline the development process and allow developers to quickly create user interfaces with rich functionality.
  • Active community — since Angular is supported by Google, it has a vast community, and you can always count on the help of experts and other enthusiasts.

React Advantages

  • Performance — React-based applications demonstrate high performance due to the usage of a virtual DOM and the JSX syntax. App performance is a crucial factor for many businesses, so ReactJS can outperform its competitors in this regard.
  • Short learning curve — JSX and components make the React library simple to learn and use. If you have basic JavaScript knowledge, you can easily get started with React.
  • Code reusability — React.js components can be reused within a project, which saves much time and improves software quality.
  • Cross-platform development — due to React Native, you can write code for web solutions and reuse it for mobile apps. What is more, React code can run in various desktop and mobile browsers.
  • SEO — React.js provides server-side rendering, which allows the search engine bots to get content in HTML files and index pages properly. For businesses, this means more traffic and more potential clients.
  • Strong community — millions of developers comprise the React community. You can ask for their help on specialized forums and groups in messengers, so no coding issue will be left unsolved.

Disadvantages of Angular and React

You should also be aware of the difficulties you may face when using Angular or React.js for frontend development.

Angular Disadvantages

  • Complexity — despite the component-based architecture, Angular remains a verbose framework with a complicated network of dependencies, so developers may spend a lot of time dealing with all the needed files.
  • Steep learning curve — Angular is not an easy tool for newbies to get started with, even if they have a JavaScript background. Mastering TypeScript, components, services and dependencies requires time and effort.
  • Limited SEO — web crawlers have trouble indexing Angular pages because they have little HTML content. To optimize them for search engines, you need third-party rendering tools, which means additional work and costs.

React Disadvantages

  • UI layers only — React.js is responsible only for the view part of your app, and you need to integrate other technologies for the complete project development. This adds complexity to the process. 
  • Frequency of updates — React’s fast development pace may seem like a downside because programmers always need to keep abreast of updates.

When to Choose React or Angular?

Summing up, we can say that React and Angular have both similarities and differences. For one project, React.js can be a good fit, but Angular may not meet all the requirements, and vice versa. Every project is unique in terms of technical, business and financial requirements. Therefore, you should make a choice depending on your specific needs.

We can only figure out some common situations when you may consider React or Angular.

ReactJS is a better choice if:

  • your team is experienced in JavaScript, HTML and CSS
  • your app is supposed to handle multiple events
  • you need to write custom components
  • your app requires high user interaction
  • you need a mobile cross-platform solution.

Angular is a better choice if:

  • your team is experienced in Angular versions, or you have time for them to master the framework
  • your team has experience with Java and C#
  • you need to build dynamic web apps
  • you need a holistic frontend framework for your project, not a library
  • you have enough resources.

Still, if you can’t decide by yourself which frontend development tool you need, you’d better consult a trusted software development company.

Which is faster, React or Angular?

Both ReactJS and Angular are fairly fast tools. It’s possible to say that React is a bit faster than Angular due to its usage of the virtual DOM.

Is Angular dying because of React?

As per Statista, 23% of developers were using Angular in 2021, while 40% of respondents reported to be using React.js. This means that React outcompetes Angular by some parameters. However, it’s not true that Angular is dying. This framework is still in high demand.

Leave a comment
  • In my opinion, it makes no sense to try to compare two good tools for frontend development. Both React and Angular are good in their own ways. Developers just should decide what exactly they need in particular situations.

  • Angular is a framework and it gives you everything to build a fully-featured application. React is a library and it allows you to build the view layer only. This is the main difference, I guess.

  • As always, it’s hard to say which tool is better if we compare two frameworks that are able to build great applications. It all depends on your needs, and the arguments provided in this article are reasonable.

  • The Angular code is a bit slower compared to React. However, both tools can provide a good performance level and can be considered for various projects.

  • If a project you are going to develop is supposed to have a lot of modules, you’d better choose Angular. With this framework, you can easily support large-scale applications.

  • The virtual DOM in React is a true helper that adds speed to your apps. I prefer developing user interfaces with this tool because of its high performance and simplicity.
