[question] voice-recognition: is for-loop on results required?

[masonlouchart]

There is 2 questions I would like to ask about this snippet.

voice-elements/src/voice-recognition.html

Lines 66 to 69 in d01df66

	for (var i = e.resultIndex; i < e.results.length; ++i) {
	that.text = e.results[i][0].transcript;
	e.result = that.text;
	}

Why the voice-recognition element is working?

Due to the prefix increment of i in the for-loop, I expect a TypeError because cannot read "0" of undefined no matter is the array length. I added a log and the i variable seems incremented after a loop.

Do we need a for-loop?

I think what we need is simply read the last entry of the results array. AFAIK, the resultIndex variable is the index of the last result received. So the for-loop do 1 loop on the last entry right?

Thanks to help me to understand how it's working. 👨‍🎓
