@ -83,6 +83,9 @@ It's not recommended to use `async` event listeners, which may lead to problems.

If an event listener must be `async`, the `e.preventDefault()` should be before any `await`,
it's recommended to put it at the beginning of the function.
If we want to call an `async` function in a non-async context,

that this is done by purpose, we want to call the async function and ignore the Promise.
