You might want to check a tutorial for the basic syntax.

There you are settings everything between ' that can only be used for one line strings. That is probably not what you are trying to do.

If you really want a multiline string, you can use the backticks. Or you can have a normal object and use JSON.stringify to turn it into a string.
