React Native

React Native develops mobile applications using JavaScript and React. On this front, both these open-source JavaScript frameworks permit mobile application development on both iOS and Android platforms.

React is an application-developing tool for the web whereas an application-developing framework for mobile devices is known as React Native. It includes all native components, as React works only with component elements.

JSX is the syntax extension that allows you to write UI elements in JavaScript. It resembles HTML tags but is converted to native components for mobile apps.

Components are used to build React Native applications. These represent different parts of the UI and can be reusable, either as functional or class components.

The state is what is meant by click here, while props are a read-only entity that is sent by a parent to a child component.

The Virtual DOM refers to a lightweight copy of the actual DOM. React Native uses it to optimize updates to the real UI to speed up things by minimizing re-renders.

That means react life cycle management; it is the place where you put your clean-up, subscription, and data fetching right after the component gets rendered.

The navigation uses all the external libraries provided by React Native such as React Navigation or React Native Navigation for stack, tab, and drawer navigation.

Redux is the state-managing library that is used in React Native to conserve the state and manage the app states. Moving on, a state that might be very complex can easily be managed across many components by Redux.

To fetch certain performance optimizations, you could minimize the number of re-renders, use FlatList for greatly long lists, lazy-load components, and optimize your images and assets.
