Hello React Native

In short, React Native Trainings allows you to build mobile apps that look, feel, and function much more like native apps. It uses the same basic user interface building blocks as regular iOS and Android apps. You simply assemble these building blocks using JavaScript and React. The good thing for developers is that they can use almost the same concepts that are used to create web apps. If you’re familiar with react or come from a front-end development background, React uses a virtual DOM that acts as a shadow of the actual available DOM. When an element changes, that change is reflected in the real DOM using the virtual DOM, using a node that corresponds to each element. However, in React Native there is no DOM instead of native components that platforms like iOS and Android provide. 

Core of JavaScript

React Native has a JavaScript Core instance to run JS code when the app is started. React Native uses the RCT Bridge Module to create a connection between the native code and the JavaScript code. Simply put, React Native brings React to mobile app development. Its goal is not to write code once and run it on any platform. The main goal is to learn it once and write it anywhere.
