Using the 'let' Function for Nullable Handling

The 'let' function in Kotlin can also be effectively used for handling nullable types. It allows you to execute a block of code only if the value is non-null, thus avoiding null pointer exceptions. This is particularly useful when you want to perform operations on a nullable variable without explicitly checking for null.

val name: String? = "John Doe"

name?.let { 
    println("The name is $it") 
} ?: run { 
    println("Name is null") 
}
