Sadly, it's a bit annoying as you can't do it that way. You'll have to do it like this:

var str = [
    "Hello, this is a       \n"
    "multiline\n",
    "       string."
].join("");

Or, using a similar trick,

var str = [
    "Hello, this ",
    "     is a multiline ",
    "string separated by new lines ",
    " with each array index"
].join("\n");
