写的牛逼，补充下下面的情况：

function* helloWorldGenerator() {
  const a = yield 'hello';
  return a;
}

__webpack_require__.r(__webpack_exports__);
/* harmony import */ var regenerator_runtime_runtime__WEBPACK_IMPORTED_MODULE_0__ = __webpack_require__(/*! regenerator-runtime/runtime */ "./node_modules/regenerator-runtime/runtime.js");
/* harmony import */ var regenerator_runtime_runtime__WEBPACK_IMPORTED_MODULE_0___default = /*#__PURE__*/__webpack_require__.n(regenerator_runtime_runtime__WEBPACK_IMPORTED_MODULE_0__);


var _marked =
/*#__PURE__*/
regeneratorRuntime.mark(helloWorldGenerator);

function helloWorldGenerator() {
  var a;
  return regeneratorRuntime.wrap(function helloWorldGenerator$(_context) {
    while (1) {
      switch (_context.prev = _context.next) {
        case 0:
          _context.next = 2;
          return 'hello';

        case 2:
          a = _context.sent; // 补充： context 上面还有个比较重要的属性是 sent
          return _context.abrupt("return", a);

        case 4:
        case "end":
          return _context.stop();
      }
    }
  }, _marked, this);
}
