javascript - JSON to JSON mapping using Mustache -

i want map input json json using mustache.

my input json like:

{   "data": [     { "catalogid": "1850", "productid": "elec004a"},     { "catalogid": "1851", "productid": "png679"}   ] } 

i want template in combine mustache tags output json.

var template = json.stringify(   {     product: [       {{#data}}       {         productid:'{{productid}}',         parentproductid:'{{catalogid}}'       }       {{/data}}      ]   } ); 

i tried using mustache tag json giving me errors. tried defining template without using json.stringify no luck!

have use mustache requirement, actual input json quite large , can't map using traditional way.

my desired output json mentioned in template mustache tags replaced relevant data input json

you don't need moustache here.

var input = {    "data": [      { "catalogid": "1850", "productid": "elec004a"},      { "catalogid": "1851", "productid": "png679"}    ]  };    var output = {    product: input.data.map(item => ({      productid: item.productid,      parentproductid: item.catalogid    }))  };    console.log(output);
