  for (let k in obj) {
    let v = obj[k];

    if (typeof v === "function") {
      v = v.toString();
    } else if (v instanceof Array) {
      v = JSON.stringify(v);
    } else if (typeof v === "object") {
      v = convert(v);
    } else {
      v = `"${v}"`;
    }

    ret += `\n  ${k}: ${v},`;
  }

  ret += "\n}";

  return ret;
}

const input = {
  data: {
    a: "@a",
    b: ["a", 2]
  },

  rules: {
    fn1: function() {
      console.log(1);
    }
  }
}

const output = convert(obj)

output

`{
  data: {
    a: "@a",
    b: ["a", 2]
  },
  rules: {
    fn1: function() {
      console.log(1);
    }
  }
