Subject Re: [FalconJx] Package down to Expression production; JSGoogEmiter prototype
Date Sun, 23 Dec 2012 10:32:11 GMT
Hi,

My personal preference for optional arguments goes to:

optArg = optArg !== 'undefined' ? optArg : defaultValue;

Which would be a line entered at the top of the function block for
each of the optional arguments, which with my current understanding of
the compiler innards seems like something that I should be able to
implement. One node -> one line.

I like your solution for the ... parameter:

rest = Array.prototype.slice.call(arguments, numberOfOtherArguments);

As a 'one liner', it neatly fits with my vey limited understanding of
the compiler innards ;-)

Thank you!

EdB
