   1 # Disallow Multiline Strings (no-multi-str)
   2
   3 It's possible to create multiline strings in JavaScript by using a slash before a newline, such as:
   4
   5 ```js
   6 var x = "Line 1 \
   7          Line 2";
   8 ```
   9
  10 Some consider this to be a bad practice as it was an undocumented feature of JavaScript that was only formalized later.
