Kotlin is packed with powerful features that help developers write clean and efficient code. One of its most underrated but game-changing features is delegation.

If you’ve ever wondered:

  • “How can I reuse functionality without inheritance?”
  • “How do I keep my code DRY (Don’t Repeat Yourself)?”
  • “Can I extend class behaviour without making it messy?”

Then delegation is the answer!

In this article, we’ll break down what delegation is, how it works, and when you should use it — all in simple terms with easy-to-understand examples!

What is Delegation?

In simple words, delegation is when a class hands over some of its responsibilities to another class instead of implementing everything itself.

  • You own a business, but you don’t do everything yourself.
