# Getting the Iteration Index in a Template Repeat

Shows how to get the iteration index when using iterative templates to
render list items:

    <template repeat="{{fruit, i in fruits}}">
      ...
    </template>

You can use the iteration index like any other variable using double mustache
(`{{}}`) syntax:

    <template repeat="{{fruit, i in fruits}}">
      <div>{{i + 1}}. {{fruit}}</div>
    </template>
