Methods
Methods are functions that are declared with a receiver which binds the method to a type. Then the method and can be used to operate on values or pointers of that type.
Notes
- Methods are functions that contain a receiver value.
- Receivers bind a method to a type and can be value or pointers.
- Methods are called against values and pointers, not packages.
- Go support function and method variables.
