Difference between old and new doRequest methods

new.js

const doRequest = async ({ accessToken, config, method, data }) => {
  const uri = generateUrl(accessToken, method, data, config);
  try {
    const req = await request({ uri });
    return JSON.parse(req);
  } catch (e) {
    console.log('Request Failed');
    throw e;
  }
};

old.js

  doRequest (requestUri) {
    return new Promise((resolve, reject) => {
      return fetch(requestUri)
        .then((response) => {
          if (response.status >= 400) {
            return reject(Boom.create(response.status, response.statusText, response));
          }
          return resolve(response.json());
        });
    });
  }
