JavaScript: Multiline Strings in Source Code

Sometimes, for reasons of clarity, it is a good idea to let a string go over multiple lines.

In JavaScript, it is not readily possible to break a string in source code just using a line break.

Unless you are using a backslash at the end of each line:

document.write("This is a text,\
reaching over two lines.");

If you close a long string with a backslash, you can simply continue the string in the next line without any problems.

Incidentally, this kind of line break "within" the string is ignored and does not have any impacts to the string. It is just the same result as if you have written the string into one line.
