# TOC Javascript and ES5 compatibility

 * Hi,
 * I’ve seen, that the JS for the TOC uses ES6 Arrow-Function Syntax in one place(
   table-of-contents.js, line 127), which does cause the TOC to not be working in
   IE11. Transpiling this line to ES5 fixes the problem.
 * Since it is only one line: Is there any chance to get backward-compatibility 
   to ES5?
 * Best regards
    Christ
