Scala replace " by \"

How to replace the double quote by \": 

val s = """I am "groot"."""

so the output will be """I am \"groot\"."""

I tried with but no luck

s.replaceAll('"', '\"')

So @Tanjin provides the correct solution. However, the reason your solution does not work is this.

s.replaceAll('"', '\"')

Backslashes have special meaning in string and character literals, so '\"' compiles down to just the quote character. Running in the REPL will show you this

scala> '\"'
res2: Char = "

Meanwhile, using triple-quote strings disables this behavior.

scala> """\""""
res3: String = \"

How does this work:

s.replace(""""""", """\"""")
