Ternary operator with undefined variables #12

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
<%= message ? message : 'No message' %>

When the variable message === undefined, the compiler throws an exception, even 
though a regular IF statement should just evaluate the expression to FALSE.

By the way, this executes correctly:

<%= typeof message != 'undefined' ? message : 'No message' %>

I am using the ejs_1.0_developer release (downloaded two days ago) as a Node.js 
module. [Cygwin environment running on Windows 7]
