+Checks if `sessionStorage` is enabled.
+
+- Use a `try...catch` block to return `true` if all operations complete successfully, `false` otherwise.
+- Use `Storage.setItem()` and `Storage.removeItem()` to test storing and deleting a value in `Window.sessionStorage`.
+
+```js
+const isSessionStorageEnabled = () => {
+  try {
+    const key = `__storage__test`;
+    window.sessionStorage.setItem(key, null);
+    window.sessionStorage.removeItem(key);
+    return true;
+  } catch (e) {
+    return false;
+  }
+};
+```
+
+```js
+isSessionStorageEnabled(); // true, if sessionStorage is accessible
+```
