How to save json data obtained through a fetch request in one or several arrays, which can later be utilized in Javascript?

edit

To save JSON data obtained through a fetch request, you can follow these steps:

1. Initialize an empty array to store the data:

let dataArray = [];

1. Make the fetch request and convert the response to JSON format:

fetch('url')
  .then(response => response.json())
  .then(data => {
    // code to store data in arrays
  });

1. Iterate through the data and push each object into the array:

data.forEach(item => {
  dataArray.push(item);
});

Alternatively, you can use the spread operator to add the data to the array:

dataArray = [...dataArray, ...data];

1. Use the array(s) as needed in your JavaScript code.
