what is e.text.value in react native code example

Example 1: color text react native

// Some code....
<Text 
	// Topic 2: Text Style
	style={styles.headline}>Hi, Lunox!
</Text>

// Some code....

headline: {
	color: 'white', // <-- The magic
	textAlign: 'center', // <-- The magic
	fontWeight: 'bold',
	fontSize: 50,
	backgroundColor: 'purple',
}
// Some code....

Look how I use it here:

Example 2: react native input

import React, { Component } from 'react';
import { TextInput } from 'react-native';

export default function UselessTextInput() {
  const [value, onChangeText] = React.useState('Useless Placeholder');

  return (
    <TextInput
      style={{ height: 40, borderColor: 'gray', borderWidth: 1 }}
      onChangeText={text => onChangeText(text)}
      value={value}
    />
  );
}
