## Callback

### yesCallback

The action performed if the condition is true.

### noCallback

The action performed if the condition is false.

## Example

In this example, we will pass a condition to check whether two values are equal using the `Logic.equal` function and print the result of the `Control.conditional` function in the console.

### 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.conditional` function to the event flow.
2. Call the function `Logic.equal` in the `condition` parameter of the function. Enter the parameters of the `Logic.equal` function.

   ```js
   value1: 20
   value2: 20
   ```

3. Call the function `Log.write` in both `yesCallback` and `noCallback` parameters of the `Control.conditional` function. Change the parameter type of the `value` parameter to `input`.

### Result

1. The console will print `YES`.
