Yup. Don't put constants at the top level.

Best to wrap you entire code in a function so everything is scoped within the function...

```auto
<script type="text/javascript">
(function() {

    const DEFAULT_WIDTH = 160
	RED.nodes.registerType('image viewer', {
        ...
    }

})();
</script>
```
