JSON.stringify replacer - how to get full path

Question

Replacer in below code write on console current processed field name

Answer 1

Something like that. You need to adjust it for arrays. I think that you can do it yourself. The idea is clear.

let a = { a1: 1, a2:1 }
let b = { b1: 2, b2: [1,a] }
let c = { c1: 3, c2: b }

function iterate(obj, path = '') {
    for (var property in obj) {
        if (obj.hasOwnProperty(property)) {
            if (typeof obj[property] == "object") {
                iterate(obj[property], path + property + '.');
            }
            else {
                console.log(path + property);
            }
        }
    }
}

iterate(c)
