Type and Function a way Go of Object-Oriented Programming(OOP)

A method is basically a function that you attach to a type

Define a person object would have name, age and more. The keywords “type” and “struct” used to define a person object.

type Person struct{
   name string
   age int
}

 a function with a type (Person) as a receiver before the function name, Go developer label it a “method”.

func (p Person) GetName() string{
    return p.name
}

The part between the “func” keyword and the function name, GetName(), is known as the receiver of the method. This method has arguments but returns a string value.

Declare a variable p with value of type Person

var p = Person{
  name: "Jason",
  age: 29,
}

 Invoke the GetName method of value p

p.GetName()
