What are props in React Component?

Props are parameters which are used to customise a component at the time of creation and on re-render. Props are like arguments passed to a React component. For example, Image is a very basic component provided by React Native library to display an image. It accepts a prop called source which is used to control what image it shows. By passing different values of props, one component can show different UI and different functionality. So we can say that props help use and reuse the same component at different places. Props are set by the parent component and remain fixed for an entire lifecycle of a component.

import React from 'react';
import { StyleSheet, Text, View, Image } from 'react-native';
import Counter from './components/Counter';
import Greeting from "./components/Greeting2";
import SimpleTextInput from './components/SimpleTextInput';
import SimpleButton from './components/SimpleButton';
import LoginForm from './components/LoginForm';
import PictureList from './components/PictureList';

export default class App extends React.Component {
  render() {
    const pictureData = {
      uri: 'https://picsum.photos/300/300'
    };
    return (
      <View style={styles.container}>
        <PictureList />
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#f5fcff',
    alignItems: 'center',
    justifyContent: 'center',
  },
  image: {
    margin: 5,
    borderRadius: 5,
    width: 300,
    height: 300
  }
});
