Why do we use ReactJs instead of Angular?

The choice between ReactJS and Angular depends on various factors such as project requirements, team expertise, scalability needs, and personal preferences. Both ReactJS and Angular are popular JavaScript frameworks/libraries used for building modern web applications, but they have different approaches and features. Here are some reasons why you might choose ReactJS over Angular:

  1. Ease of Learning: ReactJS has a lower learning curve compared to Angular. React’s simplicity and straightforward API make it easier for developers to get started quickly.
  2. Flexibility: React is primarily a library focused on the “view” layer, which means it can be easily integrated into existing projects or paired with other libraries and frameworks. On the other hand, Angular is a comprehensive framework with its opinions and conventions.
  3. Virtual DOM: React uses a Virtual DOM, which allows it to efficiently update only the necessary parts of the actual DOM, leading to better performance. This approach helps in building fast and responsive applications.
  4. Community and Ecosystem: React has a massive and active community, resulting in an extensive ecosystem of third-party libraries, tools, and resources that can aid in development.
  5. Component-Based Architecture: Both React and Angular follow a component-based architecture, but React’s component model is more straightforward and intuitive for many developers.
  6. JSX: React uses JSX (JavaScript XML) to define component structures, which enables developers to write declarative code and allows better integration between JavaScript and HTML.
  7. React Native: If you plan to build mobile applications, React Native allows you to use the same React components to create native mobile apps for both iOS and Android.
  8. Backed by Facebook: React is maintained and supported by Facebook, which means it is actively developed, and updates are regularly released.
