• Syntax brevity (reducing code size).
• Null safety (fewer NullPointerExceptions).
• Built-in support for coroutines (convenient asynchronous programming).
• Compatibility with Java (using existing libraries and frameworks).
• Extensions (adding new functions to existing classes without modifying their source code).
• Improved compilation performance in some cases compared to Java.
• Active support from Google and the community.

// Example of an extension function for String
fun String.addHello(): String {
    return "Hello, $this"
}

fun main() {
    val name = "Kotlin"
    println(name.addHello()) // Output: Hello, Kotlin
}

// Example of using the safe call operator
var text: String? = "Some text"
val lengthNonNull = text?.length // Returns null if text == null
