How To Know Which Is Best For You?

Which Is Best

Here is a quick list of the top ten questions that can be considered by any developer before jumping to the Angular or React JavaScript framework:

1. How big is the project?

All the big projects have dedicated coding needs that call for the use of Angular that has dependency injection or increased efficiencies. Hence, it helps reduce the testing time that leads to low development costs.

2. How long is it going to be maintained?

If the project has long-term maintenance needs, Angular development is perfect for such projects. However, React development is ideal for projects having short-term maintenance needs.

3. Is all of the functionality clearly defined in advance or are you expected to be flexible?

If all the app functionality is clearly defined, it is ideal to go for the Angular development. If the app development needs to be flexible, you must go for React which offers flexibility in the routing, testing, and folder structures.

4. If all of the features are already defined, what capabilities do you need?

The selection of the app capabilities out of the clearly defined features can help users select from React or Angular. Likewise, Angular is a feature-rich platform that React as it is a complete framework compared to React which is just a library.

5. Are the domain model and business logic complex?

All the complex domain models and business logic complexes are quickly handled by the Angular while React is ideal for simple app development having limited features. Further, React can be used to create UI components.

6. What platforms are you targeting? Web, mobile, desktop?

The choice of the web, desktop, or mobile platforms for app development can help decide the selection of React or Angular JavaScript framework. Angular is ideal for mobile platforms while React works well for desktop or web applications.

7. Do you need server-side rendering? Is SEO important?

Applications requiring server-side rendering can go for the Angular JS frameworks that offer quick rendering compared to the React JS framework. Further, Google offers new default libraries to make Angular apps SEO-friendly. The same is still a difficulty for the React apps.

8. Will you be handling a lot of real-time event streams?

If your app is supposed to handle a large number of real-time event streams, React is ideal for app development.

9. How big is your team?

If you’re looking for a JavaScript framework for your big tea, you can go for React while the small teams can manage app development with Angular JS frameworks.

10. How experienced are your developers and what is their background?

If your developers have limited experience then you can go for the React JS framework. Further, the technical background developers can quickly learn Angular if they already know React. 

11. Are there any ready-made component libraries that you would like to use?

Both React and Angular have ready-made component libraries. Hence, it is easy for the developers to select one out of these JavaScript frameworks based on the component library needs.
