Push values from JSON object to array and use outside function

I am writing a axios JSON data call function and want to push values from my jJSON function to use outside of the function. Is there anyways I can do that?

My Code:

let website_names = `${api}`;
   axios.get(website_names, {
      cancelToken: new CancelToken(function executor(c) {
       api_requests.website_nm = c;
    })
  })
  .then(function(website_name) {
     website_name.data.forEach(d => {
     let yoyo = [];
     yoyo.push(d.element);
     console.log(yoyo);
    });
  }).catch(function(error) {
    console.log(error);
    alert_error(error);
  });

This one gives me:

  • {element: “Google”}
  • {element: “Yahoo”}
  • {element: “Facebook”}
  • {element: “BuzzFeed”}
  • {element: “Cnet”}

I need yoyo = ["Google", "Yahoo", "Facebook", "BuzzFeed", "Cnet"]

But I also need to use yoyo outside of the axios function. I need the use of the array after it has been formed inside of axios.

    You can use map for this:

    const getWebsites = () => {
  let website_names = `${api}`;

  return axios
    .get(website_names, {
      cancelToken: new CancelToken(function executor(c) {
        api_requests.website_nm = c;
      })
    })
    .then(function(website_name) {
      return website_name.data.map(d => d.element);
    })
    .catch(function(error) {
      console.log(error);
      alert_error(error);
    });
};

getWebsites().then(yoyo => {
  //you now have the array
});

    You’re creating a new array in each iteration thereby destroying the previous. The array should be initialized outside the forEach loop:

    let yoyo = [];
website_name.data.forEach(d => {
   yoyo.push( d.element );
});
console.log(yoyo);
