When receiving JSON and attempting to store the data in a variable, I encounter an issue where it returns the error message "undefined is not iterable (cannot read property Symbol

I'm currently integrating the Advice Slip API into my project. I am experiencing an issue when trying to store the JSON data in a variable like so:

 let advice;
fetch("https://api.adviceslip.com/advice").then(response => response.json()).then(data => advice = data);

Upon executing this code, I encounter an error as mentioned. However, if I modify .then(data => advice = data) to .then(console.log) I am able to see the advice object logged in the console. Nevertheless, I require the ability to save this advice in a variable for use on my website rather than solely logging it. Therefore, I need to devise a solution that allows me to assign the retrieved advice to a variable.

Answer №1

main.js

function displayContent() {
let quote;
fetch("https://api.quotes.com/randomquote").then(response => response.json()).then(data => {
    quote = data;
    console.log(quote);
  })
}

displayContent();

Answer №2

When attempting to loop through the `advi` variable right after using the `fetch` api, it may still be undefined since the fetch call is asynchronous due to being a Web API.
