+Encodes a set of form elements as an `object`.
+
+- Use the `FormData` constructor to convert the HTML `form` to `FormData` and `Array.from()` to convert to an array.
+- Collect the object from the array using `Array.prototype.reduce()`.
+
+```js
+const formToObject = form =>
+  Array.from(new FormData(form)).reduce(
+    (acc, [key, value]) => ({
+      ...acc,
+      [key]: value
+    }),
+    {}
+  );
+```
+
+```js
+formToObject(document.querySelector('#form'));
+// { email: 'test@email.com', name: 'Test Name' }
+```
