JSON.stringify(circObj, replacerFunc());

const replacerFunc = () => {
  const visited = new WeakSet();
    return (key, value) => {
      if (typeof value === "object" && value !== null) {
        if (visited.has(value)) {
          return;
        }
        visited.add(value);
      }
    return value;
  };
};
