I tried this Link which is similar requirement to mine

But in My Case it is nested JSON I am looking for this output as below

If Is Manger=True add this count as a key Value to parent

"Key(Count)":"DirectChildrencount/TBDCount/EmployeeCount(Only who has employee number)"

Example:

{
"name":"Wendeline",
"IsManager": "TRUE",
"count":"8/4TBD/3FTE"
}

Any Help would be appreciated thanks in advance

Answer 1

We can get the DirectChildrencount using the children.length property. Further, we will make use of Array.prototype.reduce() to calculate TBDCount and EmployeeCount . We will use Array.prototype.map() to recursively iterate over the children .

Here is the code snippet that manipulates the input to obtain required output. Suppose a is your array:

const a = [ /* */ ]

const transform = x => {
    if (x.IsManager === "TRUE") {
        const child = x.children.reduce(
            (acc, curr) => {
                acc.tbd = curr.EmployeeNumber === "TBD" ? acc.tbd + 1 : acc.tbd;
                acc.fte = curr.EmployeeNumber !== "TBD" ? acc.fte + 1 : acc.fte;
                return acc;
            },
            { tbd: 0, fte: 0 }
        );
        x.count = `${x.children.length}/${child.tbd}TBD/${child.fte}FTE`;
    }
    x.children = x.children.map(transform);
    return x;
};
const b = a.map(transform);
console.log(b);

Because we are assigning output of map to x.children , you can also do:

a = [/* */];
a.forEach(transform);
console.log(a)
