Okay, I revert, "$$" in the replacement string gets replaced by "$" so its not literal.

s.split("search").join("replacement") work literally tough.

Read the specification (Ecma-262, 5.1 Edition, June 2011, page 147).
When the first parameter is a string, it treats that first parameter
literally, but it still should do substitutions in the replacement
string.

(Did you try something like "$'" in the replacement string?)
