React Native is a JavaScript framework to create real native applications for iOS and Android, based on the React JavaScript library for the creation of visual components, changing their purpose so that, instead of being executed in the browser, they run directly on the platforms. native mobiles, in this case iOS and Andorid. That is, instead of developing a hybrid or HTML5 web application, what you end up with is a real native application, indistinguishable from what you could develop with your Objective-C or Java code.

That’s the theory, but let’s see how React Native proposes to achieve this goal.

React Native uses the same fundamental paradigm of building UI blocks (visual components that the user interacts with) as real native Android and iOS applications, but manages the interaction between them using the capabilities of JavaScript and React.

As well as the use of the debugger tools developed from the Google Chrome browser, making it easier to debug code. These are five of the main features that React Native gives us by default if we choose it as the framework for our development. A priori they sound very good, don’t they? Later, in a series of articles, we will see that not everything that glitters is gold, and that all these characteristics are not always fulfilled, or not 100% fulfilled, in all cases. Support However, apart from those offered by the framework, there are other factors, just as important or more important regarding the choice of React Native as our main development tool, and it is the support it has.

We could define platform support, roughly, as the company or companies that are behind the framework or that actively use and advertise it. We all know, and it is notorious, that the main support for the React library (which, as we mentioned above, is a fundamental part of the development process in React Native) lies with Facebook.

We know that the company has built its own website and that of its sister social network Instagram. But do we know if that support extends to your mobile apps? The answer to this question is probably no (at least in my case, I didn’t know it for sure), we don’t know it with the force that we talked about React and the respective Facebook and Instagram websites, but the answer is yes, their mobile apps are developed with React Native (although the Instagram app is not supported on IPad due to framework issues).

  • Growth through innovation/creativity:
    Rather than be constrained by ideas for new products, services and new markets coming from just a few people, a Thinking Corporation can tap into the employees.
  • Increased profits:
    The corporation will experience an increase in profits due to savings in operating costs as well as sales from new products, services and ventures.
  • Higher business values:
    The link between profits and business value means that the moment a corporation creates a new sustainable level of profit, the business value is adjusted accordingly.
  • Lower staff turnover:
    This, combined with the culture that must exist for innovation and creativity to flourish, means that new employees will be attracted to the organization.
