+Creates an error dispatcher.
+
+- Use the `useState()` hook to create a state variable that holds the error.
+- Use the `useEffect()` hook to `throw` the error whenever it's  truthy.
+- Use the `useCallback()` hook to update the state and return the cached function.
+
+```jsx
+const useError = err => {
+  const [error, setError] = React.useState(err);
+
+  React.useEffect(() => {
+    if (error) throw error;
+  }, [error]);
+
+  const dispatchError = React.useCallback(err => {
+    setError(err);
+  }, []);
+
+  return dispatchError;
+};
+```
+
+```jsx
+Rconst ErrorButton = () => {
+  const dispatchError = useError();
+
+  const clickHandler = () => {
+    dispatchError(new Error('Error!'));
+  };
+
+  return <button onClick={clickHandler}>Throw error</button>;
+};
+
+ReactDOM.render(<ErrorButton />, document.getElementById('root'));
+```
