React Native is used in developing mobile applications that can run both on android/IOS, that is why you should prefer React Native. It can save you time and money. Apart from these advantages, React Native also has a lot of pre-built open-source libraries which can increase your development speed.

React Native

React Native is a JavaScript framework for developing natively rendering mobile applications for IOS and Android. It uses React, a JavaScript library for user interfaces.

Advantages of React Native

Ø Many cross-platform application development methods use the combination of HTML, CSS, JavaScript. These platforms have several drawbacks e.g. low performance. Whereas React Native does not create such an issue as it deals with the real native UI elements.

Ø It beats other cross-platforms in terms of development experience and development potential.

Ø It shrinks the size of required resources as the same piece of code can be reused multiple times during development. The developer’s team can iterate more quickly as React Native enables them to share knowledge and resources more efficiently.

Ø React Native might be considered as the mobile next step after React: It builds on the React ideas and allows you to create powerful mobile applications. In fact, React Native features an interesting extra that you will not find in the native frameworks: the ‘live reload’ feature, enabling you to immediately see the result of the latest change that you have made to the code. If you have two windows opened one containing the code and the other showing a mobile screen as a result of the code you can immediately see the effect of what you have changed in one screen, on the other screen.

Disadvantages of React Native

Ø Everything which has advantages also has some disadvantages. The same is the case with React Native. Let us look at its drawbacks.

Ø React Native adds another layer to the project thus it makes debugging more difficult. No doubt there are community guidelines about it but still, the difficulty is there.

Ø Also, React Native is a little immature platform than others. So, the drawback of new technologies also applies to it. But the good thing is in most cases the developers can solve the problem by creating missing parts of the API themselves.

Ø It is not fully cross-platform, single-code-base approach.


React Native is a cross-platform development framework. If you want to make a robust mobile application for both IOS and Android, then you can use React Native. But it comes with some drawbacks like an immature platform. But if your team can handle some uncertain issues during the development process, then it can be one of the best options for you.
