This Kotlin tutorial explores the lateinit modifier and gives several examples of how you can use lateinit in Android or other Kotlin projects.
lateinit allows you to defer initialization of non-null values so they can still be defined as non-null, but can be assigned later as in many dependency injection or test frameworks.
ex:
This is a non-null type, without a non-null initializer. Without lateinit, this would not be valid Kotlin code.

Type aliases in Kotlin allow you to provide alternative names for existing types. This is particularly useful for shortening long type names, or for providing more semantic meaning to existing types.
For example, instead of using ‘String’ you could create a type alias called ‘UserId’ that provides more information about the expected usage of that type.
💻 Examples:
'typealias UserId = String'
You can then substitute ‘UserId’ where you would otherwise use ‘String’. To the compiler, they both are treated the same.
