download json from url and turn it into object in javascript

To download JSON from a URL and turn it into a JavaScript object in the browser, you can use the fetch() function to send a request and receive a response. Then, you can extract the JSON data from the response body using the .json() method and use it as a regular JavaScript object.

Here's an example code snippet:

index.tsx
fetch('https://example.com/data.json')
  .then(response => response.json())
  .then(data => {
    console.log(data); // the parsed JSON object
  })
  .catch(error => console.error(error));

In the first line, we use the fetch() function to send a GET request to the specified URL. This function returns a Promise that resolves to the response object.

In the second line, we extract the JSON data from the response body using the .json() method, which also returns a Promise that resolves to the parsed JSON object.

In the third line, we can use the parsed JSON data as a regular JavaScript object. In this example, we log it to the console.

If any errors occur during the process, the .catch() method will catch them and log them to the console.
