+# Object
+
+`object` is a type that represents the non-primitive type, i.e. any thing that is not `number`, `string`, `boolean`, `symbol`, `null`, or `undefined`.
+
+With `object` type, APIs like `Object.create` can be better represented. For example:
+
+```ts
+declare function create(o: object | null): void;
+
+create({ prop: 0 }); // OK
+create(null); // OK
+
+create(42); // Error
+create("string"); // Error
+create(false); // Error
+create(undefined); // Error
+```
