[CS2] Quotation mark characters are escaped unnecessarily in template literals

[Inve1951]

"""<div id="unique" onclick="update('#{someVar}')"></div>"""

compiles to

`<div id=\"unique\" onclick=\"update('${someVar}')\"></div>`;

\" doesn't need escaping

Agreed that the "s don’t need to be escaped in the second example, but what’s wrong with the first? #{ isn’t supposed to interpolate in '-delimited strings.

Also, \" is harmless. It just becomes ", as if it hadn’t been escaped. So the current output works, it’s just not optimal.

it's not? i thought ' and " are interchangeable

Nope: http://coffeescript.org/v2/#strings. It’s always been that way, that’s not a v2 thing. CoffeeScript is mimicking Ruby and Bash (among others) in this regard.

i see. want to close and open a new issue or leave it?

[GeoffreyBooth]

Up to you. Maybe just edit your first post?
