How to avoid iteration on certain elements

[nareshnagpal06]

Can I have avoid repeating some elements in output even if input is an array?
For example say my input is like this

var data = [ { id: "1", name: "name1", street: "street1" }, { id: "2", name: "name2", street: "street2" }, { id: "3", name: "name3", street: "street3" }, { id: "4", name: "name4", street: "street4" } ];

and I want output like below (only one tables node).
[ { "tables": [ { id = "id1", name :"name1", street:"street1" }, { id = "id2", name :"name2", street:"street2" }, { id = "id3", name :"name3", street:"street3" }, { id = "id4", name :"name4", street:"street4" } ] } ];

but actual output seems to repeat tables 4 tables nodes. Any way out not to repeat it?

It doesn't look like you're changing much about the data. You just want to wrap the result in some extra structure.

const {
    transform
} = require("node-json-transform");

let data = [{
    id: "1",
    name: "name1",
    street: "street1"
}, {
    id: "2",
    name: "name2",
    street: "street2"
}, {
    id: "3",
    name: "name3",
    street: "street3"
}, {
    id: "4",
    name: "name4",
    street: "street4"
}];


let result = transform(data, {
    operate: [ 
        {
            run: (item) => {
                return "id" + item
            }, 
            on: "id" 
        }
    ],
});

let resultWithWrapper = [{tables: result}]

console.log("result", JSON.stringify(resultWithWrapper, 2, 2));

// and I want output like below(only one tables node).
//     [{
//         "tables": [{
//             id = "id1",
//             name: "name1",
//             street: "street1"
//         }, {
//             id = "id2",
//             name: "name2",
//             street: "street2"
//         }, {
//             id = "id3",
//             name: "name3",
//             street: "street3"
//         }, {
//             id = "id4",
//             name: "name4",
//             street: "street4"
//         }]
//     }];
