+Creates a new object, converting each key to a `Symbol`.

+- Use `Object.keys()` to get the keys of `obj`.
+- Use `Array.prototype.reduce()` and `Symbol()` to create a new object where each key is converted to a `Symbol`.
+
+```js
+const symbolizeKeys = obj =>
+  Object.keys(obj).reduce(
+    (acc, key) => ({ ...acc, [Symbol(key)]: obj[key] }),
+    {}
+  );
+```
+
+```js
+symbolizeKeys({ id: 10, name: 'apple' });
+// { [Symbol(id)]: 10, [Symbol(name)]: 'apple' }
+```
