By using "lateinit," you inform the Kotlin compiler that the property will be initialized before it is accessed, thus avoiding the necessity of providing an initial value or making the property nullable.

For instance, if you have a property that requires an object to be created during a later stage of your code (like during the setup of a view in an Android app), using "lateinit" allows you to delay its initialization without dealing with null checks or initializing it to a default value. This is especially advantageous for readability and maintaining robust code, as it makes your intentions clear and leverages Kotlin's null safety features.

The other keywords, while interesting in their own contexts, serve different purposes. For instance, "lazy" is used for properties that should be initialized only when they are accessed for the first time. "Defer" is not a keyword in Kotlin for property management and may cause confusion. "Null," while a concept related to nullability in Kotlin, does not serve as a method of property declaration and is not
