## Example

In this example, we will get the value of a global variable and print it 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 `Log.write` function to the event flow.
2. Call the function `Variable.get` inside the `Log.write` function. (\*Note: The `Log.write` function is used here for ease of demostrating the output.)
3. Specify the variable name that you would like to access.

### Result

1. If the specified global variable has previously been set (see [`set`](https://github.com/OrangeKloud/emobiq-documentation/blob/master/document/client/006-actions-and-visual-logic/action-reference/react-native/Variable/get/set/README.md)), the function will return the variable's value ("1.0.0" in this example).

2. If the specified global variable does not exist, the function will return the value in `defaultValue`.
