[Javascript] Wrap an API with a Proxy

const API_ROOT = "https://swapi.co/api";

const createApi = url => {
  return new Proxy(
    {
      headers: {
        "Content-Type": "application/json"
      }
    },
    {
      get: (target, key) => {
        return async function(id) {
          const response = await fetch(`${url}/${key}/${id}`, {}, target);
          if (response.ok) {
            return response.json();
          }

          return Promise.reject("Network error");
        };
      }
    }
  );
};
const api = createApi(API_ROOT);

export const peopleApi = api.people;
export const planetsApi = api.planets;
export const starshipsApi = api.starships;

async function go() {
  const people = await peopleApi(1);
  console.log(people);

  const planets = await planetsApi(1);
  console.log(planets);

  const starships = await starshipsApi(1);
  console.log(starships);
}

go();
