Awesome! Would it make sense to rename index.js --> UpdateDirectory.js to be more self-documenting and also leave us room to create other automation scripts?

I like that the output highlights the two different implementations of heap sort (#164) although I do not quite understand why JavaScript and Python disagree on the sort order of file names. ;-).

@sahilbansal17 We have a problem with this script in that the sort can not figure out which should come first HeapSort.js or Heapsort.js so it creates alternating updates on each commit to a pull request. In the first, s comes first. In the second, S comes first...

Is there a way to modify the script's sort so that capital S always comes before s?

Sure, I will try to fix this issue.
