Understanding React Hooks

Here is the same counter written twice. The first version is a class component, the older way to give a component memory:

import { Component } from 'react';
import { Button, Text, View } from 'react-native';

class Counter extends Component {
  constructor(props) {
    super(props);
    this.state = { count: 0 };
    this.handlePress = this.handlePress.bind(this);
  }

  handlePress() {
    this.setState({ count: this.state.count + 1 });
  }

  render() {
    return (
      <View>
        <Text>Count: {this.state.count}</Text>
        <Button title="Increment" onPress={this
