Metaprogramming (Advanced): Symbols can be used for advanced metaprogramming techniques like property name creation and dynamic property access. However, these use cases are less common and typically require a deep understanding of JavaScript intern

serializationSymbols

const serializableSymbol = Symbol.for("serializable");

class User {
  constructor(name) {
    this.name = name;
    this[serializableSymbol] = ["name", "age"]; // Mark 'name' and 'age' for serialization
  }

    const properties = [];
    for (const key in this) {
      if (
        this.hasOwnProperty(key) &&
        key !== serializableSymbol &&

      ) {
        properties.push(key);
      }
    }
    return properties;
  }
}

const user = new User("Alice", 30);
const serializableProps = user.getSerializableProperties();
console.log(serializableProps); // ['name'] (only 'name' is marked as serializable)
