getFromJsonAsync function with parameter

The getFromJsonAsync function is used to asynchronously retrieve data from a JSON source. It takes a parameter which represents the URL or file path of the JSON data source.

Here is an example:

async function getFromJsonAsync(url) {
  const response = await fetch(url);
  const data = await response.json();
  return data;
}

const jsonUrl = 'https://example.com/api/data.json';
const jsonData = await getFromJsonAsync(jsonUrl);
console.log(jsonData);

In this example, we define the getFromJsonAsync function which takes a url parameter. Inside the function, we use the fetch method to make a GET request to the specified URL. The response is then parsed as JSON using the json method available on the response object.

The await keyword is used to wait for the asynchronous operation to complete before moving on to the next line of code. This ensures that the JSON data is available before attempting to use it.

The retrieved JSON data is then returned as the result of the function. In the example, we store the returned data in the jsonData variable and log it to the console.
