Call variable names (w/ number) using for loop

Question

I'm trying to get values from req.body.answerX using for loop instead coding each of them.

I've stored values e.g. into "answer1, answer2" etc.

This was my attempt:

  for( var i = 1; i <= 10; i++){

        console.log(req.body.answer[i]);

   }

That gives me following error:

TypeError: Cannot read property '1' of undefined

How can I achieve this?

you have `req.body.answerX` at the top then `req.body.answer` in your loop, which is it? — vapurrmaid, Apr 11 '18 at 09:47

Update from

console.log(req.body.answer[i]);

to

console.log(req.body["answer" + i]);

Thanks, this worked. I started to look into way more complicated solutions. – nody Apr 11 '18 at 10:02
