This is a question on forming a template

Hello, this is a question on forming a template.

My input is :
termMarks is an array and its value can change, can be just 1 or a maximum of 4

{
"id" : "123",
"subject": [{
"name": "math"
"termMarks": [
"test1","test2","test3"
]
}]
}

Desired Output for above input :
{
"id": "123"
"terms": [
{}, {},{}
] }

Basing on the size of the termMarks array my output json should change. In the above input my "termMarks" size is 3 so I wanted the "terms" array in the output to be 3.

can someone help with a template

@rob2701, unfortunately there is no easy way to reduce arrays of arrays to a single array if you also want properties that are not in the array. In your example "name". If you only want marks themselves you can try to use jsonpath expressions

var jsonave = require('jsonave');

{
    content: {
        id: {
            dataKey: "id"
        },
        terms: {
            content: {
                 mark: {
                }
            },
            dataKey: jsonave.instance('subject[\*].termMarks[\*]')
        }
    }
}

This will give

{
    "id": "123",
    "terms": [
        {
            "mark": "test1"
        },
        {
            "mark": "test2"
        },
        {
            "mark": "test3"
        }
    ]
}
