+Creates a stateful value that is persisted to `localStorage`, and a function to update it.
+
+- Use the `useState()` hook with a function to initialize its value lazily.
+- Use a `try...catch` block and `Storage.getItem()` to try and get the value from `localStorage`. If no value is found, use `Storage.setItem()` to store the `defaultValue` and use it as the initial state. If an error occurs, use `defaultValue` as the initial state.
+- Define a function that will update the state variable with the passed value and use `Storage.setItem()` to store it.

+```jsx
+const useLocalStorage = (keyName, defaultValue) => {
+  const [storedValue, setStoredValue] = React.useState(() => {
+    try {
+      const value = window.localStorage.getItem(keyName);
