  1. Interfeces in Go

  2. Interfeces in Go

  3. None

  4. What is Interface? • abstraction • hide implementation details •

  6. Go Interface • implemented implicitly • generally defined in consumer

    • composition > inheritance

  7. Interface Pollution

  9. Takeaways • be lazy whenever you can • refrain from

    defining interface • if you need, define interface in consumer
