Is it possible to call methods created by factory function?

Question

If I compose some methods with factory function below.

function createCrudMethods() {
  return {
    findMany: async () => {
    },
    findOne: async () => {
    },
    createOne: async () => {
    },
    deleteOne: async () => {
    },
    updateOne: async () => {
    },
  };
}

Can I do something like this?

const object = {
  ...createCrudMethods();
  createOneWithNumber() {
    // do some cool stuff
    createOne() // error undefined
  }
}

or maybe there is a better way to do this?

You can make use of function scope to refer to yourself using this:

function createCrudMethods() {
  return {
    findMany: () => console.log('findMany'),
    findOne: () => console.log('findOne'),
    createOne: () => console.log('createOne'),
    deleteOne: () => console.log('deleteOne'),
    updateOne: () => console.log('updateOne')
  };
}

const object = {
  ...createCrudMethods(),
  createOneWithNumber() {
    // do some cool stuff
    console.log('createOneWithNumber');
    this.createOne();
  }
};

// Console should show:
// - createOneWithNumber
// - createOne
object.createOneWithNumber();
