Using the 'let' Function for Chaining Operations

The 'let' function is not only useful for safe calls on nullable types but also for chaining operations in a more readable way. It allows you to perform multiple operations on an object in a concise manner, improving code clarity and reducing the need for temporary variables.

val user: User? = getUser()

user?.let {
    it.updateProfile()
    it.sendWelcomeEmail()
    it.logActivity("User profile updated.")
}
