+# @babel/helper-wrap-function
+
+This helper wraps a function within a call expression. It works with any function: statements, expressions and methods; both named and anonymous.
+
+## Example
+
+**In**
+
+```js
+(function () {
+}());
+```
+
+**Out**
+
+```js
+_wrapper(function () {
+})();
+```
+
+## Usage
+
+```js
+import wrapFunction from "@babel/helper-wrap-function";
+
+wrapFunction(nodePathOfTheFunction, nodeWhichReferencesToTheWrapper);
+```
