Not in any ECMAScript implementation I have come across within now 17 years 
of experience.

A remote possibility is that this was part of a /Program/ evaluated with 
eval(), in which case it could have worked if the implementation supported 
what ECMAScript Edition 5 (2009) now specifies: multi-line string literals.

  eval("function f () { return \
{}; }");

Of course, both eval() and this notation is to be avoided.

Apparently you have yet to take the important step in the learning curve of 
thinking in terms of implementations instead of in browsers.

Or you could be considered a wannabe/troll.
