What are some advanced Kotlin techniques I should know?

Some advanced Kotlin techniques include extension functions, coroutines for asynchronous programming, and higher-order functions.

Can you explain how coroutines work in Kotlin?

Coroutines are a way to write asynchronous code in a sequential manner. They allow you to perform long-running tasks without blocking the main thread.

What are extension functions and how do I use them?

Extension functions allow you to add new functions to existing classes without modifying their source code. You define them outside the class.

Can you give me an example of a higher-order function?

Sure! A higher-order function is a function that takes another function as a parameter or returns a function. For example, fun <T> List<T>.filter(predicate: (T) -> Boolean): List<T>.
