   7 It's possible to create multiline strings in JavaScript by using a slash before a newline, such as:
   8
   9 ```js
  10 var x = "Line 1 \
  11          Line 2";
  12 ```
  13
  14 Some consider this to be a bad practice as it was an undocumented feature of JavaScript that was only formalized later.
