Millised on Kotlin keele peamised võimalused ja omadused, mida saate välja tuua?

Main features and capabilities of Kotlin:

• Java compatibility: Kotlin is fully compatible with Java, allowing the use of existing Java libraries and frameworks.
• Conciseness: the language reduces the amount of repetitive code, for example, through smart types, data classes, extension functions.
• Type safety: built-in null safety system prevents NullPointerException errors.
• Functional programming: support for lambda expressions, collections with higher-order functions.
• Coroutine model: convenient work with asynchronous code and concurrency via coroutines.

Example of data class and coroutines:

// Data class for storing data
data class User(val name: String, val age: Int)

// Example of a coroutine
import kotlinx.coroutines.*

fun main() = runBlocking {
    launch {
        delay(1000L)
        println("Hello from coroutine!")
    }
    println("Hello from main")
}
