Application development is a great world to discover, there are a large number of technologies, methodologies, software development solutions, techniques and tools created in order to create functional applications adapted to the needs of clients and users . It is therefore important to have extensive knowledge of the various existing tools, as this broadens our outlook regarding the various options we have to choose how to develop a system and in the same way a wide catalog to experiment with when perhaps one of them wasn't as functional. 

This time we want to talk about a tool for the development of native Apps, it is known as  React Native , a framework designed by Facebook  so that programmers can  create native applications for mobile devices with Javascript , a function that can also be performed with other frameworks such as  Cordova  but it differs from this since  react native is known as a bridge system , which divides the logical part of the front-end and then integrates it with native code, in this way being able to develop for different operating systems with less cost than doing it individually, since it allows code to be shared between different platforms.  

Below, we can see some of the main advantages  that developing applications with React Native brings:  

• Allows fast, fluid and efficient development. 
• Allows reusability of components. 
• They provide a native experience. 
• The same code is used and unified for the Android and iOS version. 
• It requires a smaller team  and may have a lower cost than doing it with the native languages ​​of each operating system such as Java or Kotlin. 
• Compatibility with  third-party plug-ins without the need for a webview and allows for lower memory usage.  
• Allows constant renewal and updating. 

React native is a highly recommended tool for cross platform projects, that is, those who intend to have a native interface and who want to have a version for the two most used operating systems (Android and iOS), because despite not working directly with the native languages ​​and platforms, very good quality products are obtained that provide a high-performance experience, both in the development process and in its use; It is also backed by one of the most renowned software development consulting firms and technology companies in the world, precisely an expert in applications (Facebook), which represents a great guarantee in terms of support.
