You have a single quoted string containing a backslash followed by a linefeed (newline). Unlike double quotes or unquoted strings, this has no special meaning. The string will contain a literal backslash and a linefeed.

If you wanted to break the line but not add a linefeed to the string, stop the single quote, break the line, and reopen it. This is demonstrated in the correct code.
If you wanted to break the line and also include the linefeed as a literal, you don't need a backslash:
