How To Deal With Unexpected Use Of Comma Operator No-sequences Eslint Warning

I am getting an eslint warning for unexpected use of comma. I found this answer but it does not match my issue. This is my code: const reduced = _.map(_.keys(grouped), function(e)

Solution 1:

Your return statement in the .reduce callback can be written as

  r.count += +o.amount;
  return r;

That does exactly the same thing, but it should make ESLint happy.
