+#### JavaScript: Fix ugly formatting on object destructuring with parameter decorators ([#6411] by [@sosukesuzuki])
+
+Previously, Prettier formatted decorators for destructured parameters in a weird way. Now, parameter decorators are placed just above the parameter they belong to.
+
+<!-- prettier-ignore -->
+```js
+// Input
+class Class {
+  method(
+    @decorator
+     { foo }
+  ) {}
+}
+
+// Prettier (stable)
+class Class {
+  method(@decorator
+  {
+    foo
+  }) {}
+}
+
+// Prettier (master)
+class Class {
+  method(
+    @decorator
+    { foo }
+  ) {}
+}
+```
