With type aliases, we can give a alias to other type. It's ideal for giving a name to function types like (String) -> Boolean
or generic type like Pair<Person, Person>
.
Type aliases support generics. An alias can replace a type with generics and an alias can be generics.
Type aliases is a feature of the compiler. Nothing is added in the generated code for the JVM. All aliases will be replaced by the real type.
