Я пытаюсь использовать результат моей асинхронной функции. Когда я распечатываю result на консоль, он работает нормально, и я получаю полный объект, напечатанный на консоли.

Однако, когда я пытаюсь распечатать result.data , он печатает undefined , даже если data является первым ключом объекта?

Почему я могу распечатать выходные данные функции async, но не ссылаться на значения ее объекта?

 $(document).ready(async function() {
  const date = 20190313;
  const url = 'https://api.jjjacobson.com/dailygames?season=2018-2019-regularamp;date='   date;
  let result = await executeCORSRequest(url); //async function
  console.log(result);
  console.log(result.data);
});
  

console.log(result.data) возвращает значение undefined.

Это вывод console.log(result) :

Проверьте, result является ли это строкой, которую вы должны проанализировать, используя JSON.parse() :

 let obj = JSON.parse(result);
  

Позже

 console.log(obj.data)
