What is the significance of the done property in the object returned by the next() method of a generator?
- It indicates if the generator is done executing
- It represents the final result of the generator
- It is always set to false
- It is used for error handling
The done property in the object returned by the next() method of a generator indicates whether the generator has completed its execution. When done is true, it means the generator has finished, and no more values will be generated. This is crucial for controlling the flow of iteration and termination of the generator.
In a scenario where you are extending a base class, how would overriding and extending methods impact the functionality of your derived class?
- Overriding can modify the behavior of a method in the derived class, while extending adds new functionality.
- Overriding and extending have the same impact on the derived class.
- Overriding and extending methods are not possible in ES6.
- Overriding and extending methods will lead to a compilation error.
When extending a base class in ES6, you can override existing methods in the derived class to modify their behavior. Overriding allows you to customize the functionality of inherited methods. Additionally, you can extend the base class by adding new methods in the derived class, providing additional functionality without modifying the base class. This flexibility enhances code reuse and adaptability.
