How to call function within same module

Question

My code:

export default (function () {
  (...)
  return {
    open: () => {
      (...)
    },
    close: () => {
      (...)
    },
    get: () => {
      (...)
    }
  }
})();

I wanna call the close() in get() function like this :

get: () => {
   close();
}

I tried to use this but it doesn't work.

Please give me some advice.

Thank you in advance.

Either use method properties instead (for which this rules will work just like with standard non-arrow functions):

export default (function () {
  (...)
  return {
    open() {
      (...)
    },
    close(){
      (...)
    },
    get() {
      (...)
      this.close();
    }
  }
})();

Or define all functions that you want to be able to cross-reference before the return statement:

export default (function () {
  (...)

  const close = () => {
    (...)
  };
  return {
    open: () => {
      (...)
    },
    close,
    get: () => {
      (...)
      close();
    }
  }
})();
