+
+Creates an element from a string (without appending it to the document).
+If the given string contains multiple elements, only the first one will be returned.
+
+- Use `Document.createElement()` to create a new element.
+- Use `Element.innerHTML` to set its inner HTML to the string supplied as the argument.
+- Use `Element.firstElementChild` to return the element version of the string.
+
+```js
+const createElement = str => {
+  const el = document.createElement('div');
+  el.innerHTML = str;
+  return el.firstElementChild;
+};
+```
+
+```js
+const el = createElement(
+  `<div class="container">
+    <p>Hello!</p>
+  </div>`
+);
+console.log(el.className); // 'container'
+```
