How to break strings on more than one line without concatenating?

Question

Whenever you need to write something very soon in a string in Javascript I need to concatenate, something like:

var str = 'foo bar foo bar foo bar foo bar foo bar foo bar' +
          'foo bar foo bar foo bar foo bar foo bar foo bar' +
          'foo bar foo bar foo bar foo bar foo bar foo bar' +
          'foo bar foo bar foo bar foo bar foo bar foo bar' +
          'foo bar foo bar foo bar foo bar foo bar foo bar'
;

However having to create quotation marks (") or apostrophe ', it is possible to break a string without concatenating?

Answer 1

As this response from Soen is possible using the backslash

This:

var str = "foo bar foo bar foo bar foo bar foo bar foo bar \
foo bar foo bar foo bar foo bar foo bar foo bar";

Will result in:

foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar

This:

var str = "foo\
bar";

Will result in:

obar

To break also the lines of the "value" it will be necessary to use \n and \ next:

var str = "foo bar foo bar foo bar foo bar foo bar foo bar \n\
foo bar foo bar foo bar foo bar foo bar foo bar";
