What advantages and features of Kotlin make it attractive for development?

Kotlin is attractive for development due to the following advantages:

• Java Compatibility — Kotlin is fully compatible with Java, making migration and use of existing libraries easier.
• More concise and expressive syntax — reduces boilerplate code, increasing readability.
• Type safety and null-safety — helps avoid common null-related errors.
• Support for functional programming — lambda expressions, extension functions, and other features.
• Coroutine model for asynchronous programming — simplifies working with threads and asynchronous tasks.

Example of simple Kotlin code:

fun greet(name: String?): String {
    return "Hello, ${name ?: "Guest"}!"
}

Here, the Elvis operator (?:) is used to handle nulls, making the code safe and concise.
