In order to modify the function to be asynchronous, you can use the async
and await
keywords. Here's an example:
async function downloadFile(url) {
try {
const response = await fetch(url);
const data = await response.blob();
return data;
} catch (error) {
console.error(error);
}
}
In this example, the downloadFile
function is now marked as async
. Inside the function, we can use await
to make sure that each operation, such as fetching the data, is complete before moving on to the next step. The try...catch
block allows you to handle any errors that might occur during the asynchronous operation.
Note that if you're calling the downloadFile
function from another function, you'll need to make sure that function is also marked as async
and you use await
when calling downloadFile
.
