Mustache.js Index of array loops

When using mustache as the template engine, you want to take advantage of the index sort of the objects in the array, but find that the array index is not available in mustache, and after a search, it is possible to add an index to the object of the array, as shown below

/html{{#data}}    <span>{{index}}</span>//want index to increment as the loop progresses, the first thought of course is the index of the array, But mustache cannot get {{/data}}//jsvar data = [    {"name": "A",    "age": 12 },    {"name": "B",    "age": "+"}]; // The index can be indexed in the JSON object you want to use  for (var i=0;i<data.length;i++) {        = i;    }

This enables the index to accumulate.
