Components

Components are the building blocks. They are built all-around react. React is a set of nested components.

JSX

JSX is the coexistence of HTML and JAVA to create a better app framework. Combining them makes the app more useful.

Attributes – Props

Props are how different components co-relate with one another. Props are used when one command is parent, and another is the child command. So props flow from parent to child.

Attributes – State

React Native offers unidirectional flow, but if multiple resources require giving instructions to a source, then the state is used.

APIs

APIs uniquely interacts with React Native. It has a unique configuration and has commands like render and setState, which are particular to React Native.

How do components work?

A prop’s object as an argument is accepted by a functional component, and the output is an HTML code. Functioning like a template, it gives structure and the Java code can be used according to the user’s choice.
