コード(Emacs)

/*jslint         node    : true, continue : true,
  devel  : true, indent  : 2,    maxerr   : 50,
  newcap : true, nomen   : true, plusplus : true,
  regexp : true, sloppy  : true, vars     : false,
  white  : true
*/
var numbers = [3, 2, 1],
    str = ' is bigger than ';

console.log(numbers.join(str));

入出力結果(Terminal)

$ jslint sample4.js
