    You are free to use this in any way you want, in case you find this useful or working for you.
  
    Usage:
      js_beautify(js_source_text);
      js_beautify(js_source_text, options);
  
    The options are:
      indent_size (default 4)          — indentation size,
      indent_char (default space)      — character to indent with,
      preserve_newlines (default true) — whether existing line breaks should be preserved,
      preserve_max_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk,
  
      jslint_happy (default false) — if true, then jslint-stricter mode is enforced.
  
              jslint_happy   !jslint_happy
              ---------------------------------
               function ()      function()
  
      brace_style (default "collapse") - "collapse" | "expand" | "end-expand" | "expand-strict"
              put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line.
  
              expand-strict: put brace on own line even in such cases:
  
                  var a =
                  {
                      a: 5,
                      b: 6
                  }
              This mode may break your scripts - e.g "return { a: 1 }" will be broken into two lines, so beware.
  
      space_before_conditional: should the space before conditional statement be added, "if(true)" vs "if (true)"
  
      e.g
  
      js_beautify(js_source_text, {
        'indent_size': 1,
        'indent_char': '\t'
      });
