 This way we can pass a property like `index` for operations requiring those. To insert this object to multiple arrays, of course we do:
 
 ```ts
-{ id: '2', name: 'New book', __insert: { arrayTypes: ['books', 'favouriteBooks'], index: 1 } }
+{
+  id: '2',
+  name: 'New book',
+ _insert: { arrayTypes: ['books', 'favouriteBooks'], index: 1 },
+}
 ```
 
 So like before, we can just pass array of array types. Ok, but what, if we need to set different indexes for different array types?
 
 ```ts
-{ id: '2', name: 'New book', __insert: [{ arrayType: 'books', index: 1 }, { arrayType: 'favouriteBooks', index: 2 }] }
+{
+  id: '2',
+  name: 'New book',
+  __insert: [{ arrayType: 'books', index: 1 }, { arrayType: 'favouriteBooks', index: 2 }],
+}
 ```
 
 As you can see, you just pass array of operation configs, so that each array type can have dedicated properties.
 
 And what, if you would like to multiple operations to one node? Easy:
 
 ```ts
-{ id: '2', name: 'New book', __append: 'favouriteBooks',  __insert: { arrayTypes: 'books', index: 1 } }
+{
+  id: '2',
+  name: 'New book',
+  __append: 'favouriteBooks',
+  __insert: { arrayTypes: 'books', index: 1 },
+}
 ```
 
 You just add multiple meta operation properties to the same object.
