 If the <i>important</i> property is missing, we will default the value to <i>false</i>. The default value is currently generated in a rather odd-looking way:
 
 ```js
-important: Boolean(body.important) || false,
+important: body.important || false,
 ```
 
 If the data saved in the _body_ variable has the <i>important</i> property, the expression will evaluate its value and convert it to a boolean value. If the property does not exist, then the expression will evaluate to false which is defined on the right-hand side of the vertical lines.
