+### Toggle
+
+Renders a toggle component.
+
+The `state` of the component default to `false` and bind the `handleClick` method to the component's context.
+Use an object, `style`, to hold the styles for individual components and their states.
+Create a method, `handleClick`, which uses `Component.prototype.setState` to change the component's `state` from toggleOn to toggleOff and vice versa.
+In the `render()` method, destruct `state` and `style` to abbreviate typing, use a  `<button>` that alters the component's `state`.
+Determine the appearance of the content, based on `state.isToggleOn` and apply the appropriate CSS rules from the `style` object.
+
+```jsx
+class Toggle extends React.Component {
+  constructor(props) {
+    super(props);
+    this.state = {
+      isToggleOn: false
+    };
+    this.style = {
+      on: {
+        backgroundColor: 'green'
+      },
+      off: {
+        backgroundColor: 'grey'
+      }
+    };
+
+    this.handleClick = this.handleClick.bind(this);
+  }
+
+  handleClick() {
+    this.setState(state => ({
+      isToggleOn: !state.isToggleOn
+    }));
+  }
+
+  render() {
+    const { isToggleOn } = this.state;
+    const { on, off } = this.style;
+
+    return (
+      <button
+        onClick={this.handleClick}
+        style={isToggleOn ? on : off}
+      >
+        {isToggleOn ? 'ON' : 'OFF'}
+      </button>
+    );
+  }
+}
+```
+
+```jsx
+ReactDOM.render(<Toggle />, document.getElementById('root'));
