Dealing with long words in headers - a recursive approach

Using long words in headers is usually no problem on websites, but when it comes to mobile views it can become one. I stumbled over this problem in one of my projects:

The shown content comes from a content management system, so hyphens are no solution here. Using word-break does not look good either. So I came up with a little recursive function in javascript to solve this:

function fixHeader(header){       
  if($(header).get()[0].scrollWidth>$(header).parent().width()){
    $(header).css("font-size", (parseInt($(header).css("font-size"))-1)+"px");
    fixHeader(header);
  }
}

This approach uses jQuery, but it's also possible to use javascript only. It reduces the size of the header until it the longest word fits in the container. To use the function just call

fixHeader($('#element_to_fix'));
