Which part of the spec makes you think it only works incidentally? http://www.ecma-international.org/ecma-262/6.0/#sec-array.from http://www.ecma-international

  The part where you're abusing an old "array like" and the way Array.from works with it and uses the index argument in the mapper argument to force it into a range. How many people do you think understand what `Array.from({length: 5})` works?

    Your comment sounded like it only worked because of implementation details in the JS engines. That would have been a much bigger deal than just not liking the style. Out of curiosity, how would you do it yourself?
