Disallow Multiline Strings (no-multi-str)

It’s possible to create multiline strings in JavaScript by using a slash before a newline, such as:

var x = "Line 1 \
         Line 2";

Some consider this to be a bad practice as it was an undocumented feature of JavaScript that was only formalized later.

Rule Details

This rule is aimed at preventing the use of multiline strings.

The following generates a warning:

var x = "Line 1 \
         Line 2";

The following does not generate a warning:

var x = "Line 1\n" +
        "Line 2";

This rule was introduced in ESLint 0.0.9.
