Accessing Array from repeat in Polymer -


if have template-repeat tag this: 

<template id="t" repeat="{{i in outputfields}}">   {{i.name}}   <template ref="t" repeat="{{i in i.childoutputfields }}"></template> </template>

i able acccess current array in template iterating on can add this:

  <template if="{{i != currentarray[currentarray.length-1] }}">   ,</template>

where currentarray array template iterating over.

is there way array being iterated over?

polymer supports array indexing in template repeat so:

<template repeat="{{item, in items}}">   {{item}}<span hidden?="{{i == items.length - 1}}">,</span> </template>
