Enum in JavaScript

Scripting
1

Hi guys,i am learning actually unity…
my question is:
in JS how can i declare enum?

i used this structure:

private enum ERot{Left=-1,none=0,Right=1
}
(after i want to assign a variable to ERot like var state:ERot;)
i declared this before update function in the upper part of the code…

what i am doing wrong?

i need a class to do this?
