How can I correctly print object information in logs when console.log shows only [object Object]?

  let obj: Record<string, Object> = { name: 'abc', id: 123 };
  let param: HashMap<string, Object> = new HashMap<string, Object>();
  param.set('obj', obj);

  console.log(`param info (raw): ${param.get("obj")}`);                  // → [object Object]
  console.log(`param info (json): ${JSON.stringify(param.get("obj"))}`); // → {"name":"abc","id":123}
  Tips: If there may be circular references, use a replacer:
  const safeStringify = (v: unknown) => {
    const seen = new WeakSet();
    return JSON.stringify(v, (k, val) => {
      if (typeof val === 'object' && val !== null) {
        if (seen.has(val)) return '[Circular]';
        seen.add(val);
      }
      return val;
    });
  };

  let obj: Record<string, Object> = { name: 'abc', id: 123 };
  let param: HashMap<string, Object> = new HashMap<string, Object>();
  param.set('obj', obj);

  const val = param.get('obj') as Record<string, Object>;
  console.log(`param name: ${val['name']}, id: ${val['id']}, typeof: ${typeof val}`);
  // → param name: abc, id: 123, typeof: object
