The basics of methods: Smart Go

This video tutorial explains the concept of methods in Go, highlighting their role in creating object-oriented behaviors. It covers how to define methods using structs, the use of pointers to modify original values, and the invocation of methods. The tutorial also discusses method overloading and naming conventions in Go, providing a comprehensive understanding of how methods work in this programming language.

What is the closest parallel to a class in Go?

• Package

• Module

• Struct

• Interface

In the example provided, what is the purpose of the 'add role' method?

• To print the details of a movie

• To remove a role from a movie

• To create a new movie instance

• To append a cast member to a movie's roles

Why is it generally a good idea to use a pointer receiver in methods?

• To simplify the code

• To avoid copying large structs

• To ensure type safety

• To increase the execution speed

What happens when you call a method with a pointer in Go?

• The method will convert the pointer to a value

• The method will automatically receive a pointer

• The method will always return an error

• The method will ignore the pointer

How can methods with the same name coexist in Go?

• By being in different packages

• By being defined in different files

• By having different return types

• By accepting different types for their method
