The @babel/helper-function-name package is a utility that is used within the Babel compiler. It helps in the process of naming function expressions, particularly in situations where a function does not have an explicit name. This can be useful for debugging purposes, as it allows for better stack traces by providing names to otherwise anonymous functions.

What are @babel/helper-function-name's main functionalities?

Naming Function Expressions

This code sample demonstrates how the @babel/helper-function-name package can be used to name the class methods within the transpiled code. The package helps to assign names to the class methods that are created using the Babel transpiler, which would otherwise be anonymous.

"use strict";

var _interopRequireDefault = require("@babel/runtime/helpers/interopRequireDefault");

var _classCallCheck2 = _interopRequireDefault(require("@babel/runtime/helpers/classCallCheck"));

var _createClass2 = _interopRequireDefault(require("@babel/runtime/helpers/createClass"));

var MyClass = /*#__PURE__*/function () {
  function MyClass() {
    (0, _classCallCheck2["default"])(this, MyClass);
  }

  (0, _createClass2["default"])(MyClass, [{
    key: "myMethod",
    value: function myMethod() {}
  }]);

  return MyClass;
}();
