+
+Unescapes escaped HTML characters.
+
+- Use `String.prototype.replace()` with a regexp that matches the characters that need to be unescaped.
+- Use the function's callback to replace each escaped character instance with its associated unescaped character using a dictionary (object).
+
+```js
+const unescapeHTML = str =>
+  str.replace(
+    /&|<|>|'|"/g,
+    tag =>
+      ({
+        '&': '&',
+        '&lt;': '<',
+        '&gt;': '>',
+        '&#39;': "'",
+        '&quot;': '"'
+      }[tag] || tag)
+  );
+```
+
+```js
+unescapeHTML('&lt;a href=&quot;#&quot;&gt;Me &amp; you&lt;/a&gt;');
+// '<a href="#">Me & you</a>'
+```
