Replacement for rendering.inBackend() in prototype?

I would like to add “trigger”-className for javaScript-code only in Frontend, because editing is a little confusing, with animatted stuff.
Within this nodeType I have a lot of other classes to add with conditions. All of them I wrapped in prototype: Works fine!
Unfortunatelly I can’t find the replacement for viewHelper’s rendering.inBackend() to check in prototype-process, if class is needed (Frontend) or should omitted (Backend)?

Could anybody please point me to the right docu-part or workaround?

EEL: ${node.context.inBackend}
