There are no guarantees in this field.  Code that works here today may break 
elsewhere or tomorrow.  One can only write code as robust as reasonably 
possible so that it is less likely to break there or then.

The general idea of jsx.dom.createEventListener() is that if your listener 
code is written to the W3C DOM Events API and you are sure that your target 
environments support that, you do not need to call it.
