Detailed Side-by-Side Comparison: React vs Angular
Let’s compare Angular and React in detail.
1. Popularity: Angular vs React
Both frameworks are popular in the developer community, but which one is more popular? React has the upper hand with 203k stars on GitHub, while Angular has 86.7k stars. In a Statista survey conducted in 2022, React secured the second position while Angular was fifth.
Angular gained popularity for building single-page applications since its initial release as AngularJS in the early 2010s. It is a mature framework that has evolved and improved with new releases. However, competition from JS frameworks like Vue.js and React has affected its popularity.
React has consistently maintained more popularity than Angular. Its features, such as rendering optimizations, virtual DOM, and easy migration between versions, make it the go-to front-end framework for dynamic web applications. The simplicity of reusing UI components also makes it easy to get tasks done.
2. Performance: Angular vs React
Angular uses bidirectional data binding, which requires a watcher to monitor each binding. The loop continues until all watchers and their values have been confirmed. This bidirectional data binding process may potentially impact Angular’s performance. However, this may improve with the inclusion and enhancement of the new technology Ivy in Angular.
React outperforms Angular regarding runtime performance because its Virtual DOM trees are lightweight and built on the server. Additionally, React uses unidirectional data binding, which does not require the allocation of watchers, resulting in a reduced workload.
3. Data Binding: Angular vs React
React differs significantly from Angular in its approach to state management; React prefers libraries like Helmet and React Router, while Angular relies on built-in data-binding. Redux may be combined with React to provide unidirectional data flow with immutable data structures.
Angular uses two-way data binding, so any changes to any interface element automatically update the model state. This approach keeps all layers of an application in sync as Angular connects HTML elements directly with model variables so they not only display but also modify backend data in real-time. It is particularly suitable for large-scale software that addresses complex requirements, such as medical and accounting software; making Angular an excellent choice when developing ERP software solutions.
It uses one-way data binding, rendering modifications to its interface model only after updating its state. As a result, whenever components change without any modifications made by React itself, its state remains unchanged; giving developers more control over web and mobile apps. Rather than following an automated approach for data binding, React uses one-way binding with two-way data binding helpers to accommodate complex object manipulation or parsing work.
4. Components: Angular vs React
The Angular framework comprises three components, namely Models, Views, and Controllers. However, the Angular app structure is rigid and intricate. It allows developers to split the code into separate files for reusing templates and codebases in other projects.
Unlike Angular, React doesn’t have a predetermined format for writing code. Its codebase is well-organized and readable. The component trees in React provide a logical arrangement of code. Declarative component declarations are used in functional programming.
5. UI Components: Angular vs React
Angular offers several material design components like buttons, layouts, and pop-ups, allowing easy and swift UI configuration.
To use material design components in React, you must install Material-UI Library and its dependencies. The community develops these UI tools and provides numerous UI components, including free and paid options.

6. DOM: Angular vs React
Angular uses a real DOM, a graph representing a user’s browser view. However, updating the real DOM is costly in terms of performance. To mitigate this, Angular uses change detection to find and update only components that require changes.
React uses a virtual DOM, a lightweight copy of the real DOM, to update only the necessary elements without re-rendering the entire tree structure. This approach makes React more efficient than Angular in terms of runtime performance.
7. Tools: Angular vs React
It has many built-in features such as data binding, project building, and component-based routing, eliminating external libraries. However, state management frameworks like NgRx and RxJS can be used to enhance Angular’s capabilities.
It relies more on external state management libraries like Helmet, Redux, and React Router to optimize state management, API interaction, and routing. But React’s core library is lightweight and efficient, making it easier to work with.
8. Server-side rendering: Angular vs React
It allows for server-side rendering by creating a static view before the application becomes fully interactive. Using a combination of JSON and client-side caching, Angular can effectively reduce the traffic between the client and server.
It can easily render applications to the server to make them SEO-friendly. This can be done by calling specific functions such as RenderToString or renderToStaticMarkup. React is known for its flexibility, which makes it a popular choice among developers.
9. Testing: Angular vs React
It requires several tools to conduct various forms of testing, with mocking an important aspect as it ensures data is obtained without flakiness or errors. React offers test runners like Mocha, Ava, and Jest, allowing developers to run tests during development processes.
10. Optimizing the bundle size: Angular vs React
The bundle size is critical, especially for larger apps. Code-splitting and compression can be used to optimize increasing bundle sizes without affecting performance.
11. Learning curve: Angular vs React
It has a vast and dynamic framework that covers many topics, such as directives, modules, components, services, and dependency injections. As a result, the learning curve for Angular is higher than for React. However, Angular is well-suited for solving complex problems in large-scale applications.
It has a simpler learning curve, focusing on writing components, managing internal states, and using props for configuration. While React may require developers to learn the basics of state management and routing library, it is generally easier than Angular.

React vs Angular: When to choose which?
Choose React if you want a lightweight library with greater flexibility, faster rendering, and no challenging learning curve. If you want a full-featured framework with better tooling, a strong, opinionated approach, and easier server-side rendering, go with Angular. Before making a decision, consider your project requirements and team skills.
React and Angular to determine which framework to use for your project. Both are great for building modern mobile and web applications with component-based architectures. The choice ultimately depends on your project requirements, preferred programming paradigm, project workflows, and the skills of your developers.
When comparing Angular and React (Angular vs React Advantages and Disadvantages), React is simpler and emphasizes component reusability, while Angular is more comprehensive and self-sufficient but initially more challenging. However, Angular’s long-term benefits justify the learning curve. Overall, React focuses on UI components, while Angular offers a broader range of features, making it a matter of preference and project requirements.
React is ideal for small teams that want to build applications quickly with a short learning curve. Despite its steeper learning curve, Angular is a better choice for larger development teams building angular vs react for enterprise applications.
React is best for small to medium-sized applications and projects focusing on reusable UI components. At the same time, Angular is more suitable for large-scale enterprise applications with complex features and workflows.
Although React has an easier learning curve, Angular’s platform can be more expansive. Once understood thoroughly, Angular allows developers to develop larger projects (than with React) quickly.
Your choice depends entirely upon the specific needs of your project. React is ideal for creating large, complex apps with lots of data flowing among components; while Angular provides excellent enterprise-scale data management and scalability features.
React and Angular have unique learning curves, though React tends to be simpler for beginners due to its simpler syntax and smaller API surface area; on the other hand, Angular presents more challenging obstacles due to its extensive feature set.
