-For such checks you can also ommit the `instanceof String` and use an [`Elvis`](elasticsearch://reference/scripting-languages/painless/painless-operators-reference#elvis-operator) such as `if: ctx.user?.geo?.region?.isEmpty() ?: false`. This will only work when region is a String. If it is a double, object or any other type that does not have an `isEmpty()`function it will fail with a `Java Function not found` error.

 One common thing I use it for is when dealing with numbers and casting. The field specifies the usage in `%`, however Elasticsearch doesn't like this, or better to say Kibana renders % as `0-1` for `0%-100%` and not `0-100`. `100` is equal to `10.000%`

 This allows me to always set the `cpu.usage` field and not to worry about it, have an always working division. One other way to leverage this, in a simpler script is like this, but most scripts are rather complex so this is not that often applicable.

 Most safest and secure option is to write:
 
-- `ctx.message instanceof String && ctx.message.startsWith('shoe')`  
+- `ctx.message instanceof String && ctx.message.startsWith('shoe')`
 - `ctx.event?.category instanceof String && ctx.event.category.startsWith('shoe')`
 
 The reason for that is, if `event.category`  is a number, object or anything other than a `String` then it does not have the `startsWith` function and therefore will error with function `startsWith` not available on type object.
