Using the 'let' Function for Nullable Type Handling

The 'let' function is particularly useful when dealing with nullable types in Kotlin. It allows you to execute a block of code only if the value is not null. This can help avoid null pointer exceptions and make your code cleaner and more concise. By using 'let', you can safely operate on the nullable object and provide an alternative action if it is null.

val name: String? = "Kotlin"
name?.let { 
    println("Hello, $it!") 
} ?: run { 
    println("Name is null") 
}
