⚗️ add a utility js to get automatically json files from api using request

/**

 * Parses the JSON returned by a network request

 *

 * @param  {object} response A response from a network request

 *

 * @return {object}          The parsed JSON from the request

 */

function parseJSON(response) {

    if (response.status === 204 || response.status === 205) {

        return null;

    }

    return response.json();

}

/**

 * Checks if a network request came back fine, and throws an error if not

 *

 * @param  {object} response   A response from a network request

 *

 * @return {object|undefined} Returns either the response, or throws an error

 */

function checkStatus(response) {

    if (response.status >= 200 && response.status < 300) {

        return response;

    }

    const error = new Error(response.statusText);

    error.response = response;

    throw error;

}

/**

        .then(checkStatus)

        .then(parseJSON);
