I'm trying to manipulate my response data in a way that each set of data group as a array 'years. So i made a loop to check every correspondent value associate by it Year, to group like.:
vm['years'][0] = (Array(12)),
vm['years'][1] = (Array(12)),
vm['years'][2] = (Array(8)),
vm['years'][3] = (Array(5)),
...
So theres my script:
<script type="text/javascript">

if the response has 34 lines, then you should get an error when you try
response[34].year– Jaromanda X Commented Jan 17, 2018 at 1:23

Reset to default 2The error es from the fact that response[x] is undefined. Using response[x].year is like accessing undefined.year which is an error, so using:
if ( response[x].year === undefined )
as a guard also causes the same error because you are still trying to access response[x].year. You should use this as a guard instead:
if ( response[x] === undefined )
Personally, I would do something this instead:
