  a = 1,
  b = 'foo',
}
console.log(TestEnum.a, TestEnum.b)

// before
export let TestEnum
;(function (TestEnum) {
  TestEnum[(TestEnum.a = 1)] = 'a'
  TestEnum.b = 'foo'
})(TestEnum || (TestEnum = {}))

console.log(TestEnum.a, TestEnum.b)

// after
const TestEnum = {
  a: 1,
  '1': 'a',
  b: 'foo',
}
console.log(1, 'foo')
