Takeaways

• 💡 React is a JavaScript library for UI development, maintained by Facebook and supported by a large open-source community.
• 🚀 Angular is a TypeScript-based open-source framework developed by Google, designed for both web and mobile development.
• ⚡ React offers better performance due to its Virtual DOM, which minimizes browser load and speeds up rendering.
• 🐢 Angular’s performance can lag in complex apps because of bi-directional data binding, though recent updates have improved efficiency.
• 📘 React has a gentler learning curve for JavaScript developers but often requires learning additional libraries like Redux for state management.
• 🏗️ Angular is a full-featured MVC framework with a steeper learning curve but provides everything needed without relying on external libraries.
• 🌍 React has broader adoption and is used by major companies such as Facebook, Netflix, Twitter, Airbnb, and The New York Times.
• 🏢 Angular powers applications at companies like Google, Apple, Nike, McDonald’s, and Gmail, which benefits from preloaded browser functionality.
• 📈 Industry trends show React’s popularity growing steadily, while Angular’s popularity remains relatively stable according to Google Trends data.
• 💰 React developers earn higher average salaries than Angular developers in both the US and India, reflecting stronger market demand.
• 🧠 React is simpler and faster to get started with, while Angular offers a more complete development ecosystem for long-term projects.
• ⚖️ Ultimately, choosing between React and Angular depends on personal preference, skills, and project needs—there is no clear winner.

Q & A

What is React and who manages it?

React is a JavaScript library for UI development, primarily managed by Facebook. It has an open-source community of developers and was introduced in May 2013.

How does Angular differ from React in terms of its nature?

Angular is a full-fledged TypeScript-based JavaScript framework for both web and mobile development, managed by Google. It was launched in September 2016 as a complete rewrite of AngularJS, and it competes directly with React.

What performance advantage does React offer over Angular?

React's performance is improved with the use of a Virtual DOM, which reduces the load on the browser. It only updates the necessary components instead of reloading the entire page, making it faster, especially in dynamic applications.

Why does Angular perform worse in some cases compared to React?

Angular uses a traditional DOM, which updates the whole page even if a single element changes. This can make it slower, particularly in complex or dynamic applications. However, recent updates to Angular have significantly improved its performance.

What is the learning curve like for React compared to Angular?

React has a simpler learning curve for developers familiar with JavaScript. However, additional libraries like Redux are needed for state management. In contrast, Angular is more complex due to its integrated MVC framework, requiring developers to learn TypeScript and other embedded tools.

What type of community support does React offer?

React has a large and active global community. Although sometimes documentation can be lacking, the community support compensates for this, helping developers troubleshoot and learn.

How does Angular's community support compare to React's?

Angular has a smaller community compared to React, but it has strong and well-organized documentation. Over the years, the community support for Angular has improved, helping developers navigate the framework more effectively.

Which companies and applications use React, and why is it preferred?

React is used by large companies like Facebook, Twitter, Netflix, and Airbnb. Its popularity is mainly due to its simplicity, flexibility, and fast rendering, particularly in dynamic, high-performance applications. For example, New York Times uses React to keep web pages fast and smooth without reloading the entire page.

Can you give an example of a company that uses Angular?

Angular is used by companies like Google, Apple, Nike, and McDonald's. One of the most notable examples is Gmail, which benefits from Angular's ability to preload content for smoother interactions after the initial load.

How do React and Angular compare in terms of market trends and job opportunities?

React's popularity has been steadily increasing over the years, while Angular's popularity has remained relatively stable. In terms of job trends, React developers earn higher salaries. In the US, the average salary for a React developer is around $91,000 per year, whereas Angular developers earn around $73,000. In India, React developers make about 7.35 lakhs per annum, and Angular developers earn around 4.88 lakhs.
