• Void： Represents a type that does not return a value

Detailed description

Value type：

• Stored on the stack.
• Contains values ​​directly, rather than references to other values ​​or objects.
• When copying, create a copy of the value.

Reference type :

• is stored in the heap.
• Contains a reference to another object or value.
• When copying, create a reference to the original object.

Other types:

• Null: Represents a missing or uninitialized value.
• Dynamic: Does not check types at compile time, allowing types to be determined dynamically at runtime.
• Void: Usually used for the return type of a method or function, indicating that the method or function does not return any value.
