How to put parameters to faker functions?

Trying to send parameter to zipCode function but it can't handle this

Error: faker.address.zipCode('#####') is not a function

# path may vary depends on your base docker image
const faker = require('/usr/local/lib/node_modules/pg-anonymizer/node_modules/faker');

module.exports = {
  generateCity: (val) => {
    # use faker whatever you want
    let city = faker.address.city();
    return city.substring(0, 15);
  }
};
