Using the 'let' Function for Nullable Types

The 'let' function is particularly useful when working with nullable types in Kotlin. It allows you to execute a block of code only if the variable is not null, providing a safe way to handle optional values. This avoids the need for explicit null checks and helps keep your code clean and concise.

val name: String? = "Kotlin Developer"

name?.let {
    println("Hello, $it!")
} ?: println("Name is null")
