+### `decorateObject(object, map)`
+
+Decorates an object the same way `decorateClass()` decorates a class:
+
+```js
+import { decorateObject } from '@vates/decorate-with'
+
+const object = {
+  get bar() {
+    // body
+  },
+
+  set bar(value) {
+    // body
+  },
+

+    // body
+  },
+}

+decorateObject(object, {
+  // getter and/or setter
+  bar: {
+    // without arguments
+    get: lodash.memoize,
+
+    // with arguments
+    set: [lodash.debounce, 150],
+  },
+
+  // method (with or without arguments)
+  baz: lodash.curry,
+})
+```
+
 ### `perInstance(fn, ...args)`
 
 Helper to decorate the method by instance instead of for the whole class.
