## Example

In this example, we will clearInterval by interval id.

**\* Note:** Must have working `Control.interval` function with it's interval id in order for this function to work.

### Steps

1. Drag a `button` component into the canvas and open the `Action` tab. Select the `press` event of the button and drag the `Control.clearInterval` function to the event flow.

2. Put a `Log.write` function inside the event flow and change the param type to function.

3. Put function `Control.clearInterval` inside `Log.write` function. Enter the parameters of the `Control.clearInterval` function.
