+### useFetch
+
+A hook that implements `fetch` in a declarative manner.
+
+- Create a custom hook that takes a `url` and `options`.
+- Use the `React.useState()` hook to initialize the `response` and `error` state variables.
+- Use the `React.useEffect()` hook to anychronously call `fetch()` and update the state varaibles accordingly.
+- Return an object containting the `response` and `error` state variables.

+```jsx
+const useFetch = (url, options) => {
+  const [response, setResponse] = React.useState(null);
+  const [error, setError] = React.useState(null);
+
+  React.useEffect(() => {
+    const fetchData = async () => {
+      try {
+        const res = await fetch(url, options);
