-# Animated circle with callback

-In the task <info:task/animate-circle> an animated growing circle is shown.

-Now let's say we need not just a circle, but to show a message inside it. The message should appear *after* the animation is complete (the circle is fully grown), otherwise it would look ugly.
-
-In the solution of the task, the function `showCircle(cx, cy, radius)` draws the circle, but gives no way to track when it's ready.
-
-Add a callback argument: `showCircle(cx, cy, radius, callback)` to be called when the animation is complete. The `callback` should receive the circle `<div>` as an argument.
-
-Here's the example:

```js
showCircle(150, 150, 100, div => {
-  div.classList.add('message-ball');
-  div.append("Hello, world!");
});
```

-Take the solution of the task <info:task/animate-circle> as the base.
