How to Create Custom Types in Golang?

In Go, creating custom types is typically done using the type keyword. There are several approaches to define custom types:

1. Defining a new type based on an existing type: This method enhances code readability and maintainability by leveraging an existing type.

   go
   type MyInt int

2. Structures: Structures are composite data types consisting of fields, each with its own type and name.

   go
   type Person struct {
       Name string
       Age  int
   }

3. Interfaces: Interfaces define a set of methods that a variable must implement, serving as abstract types to specify common behaviors across different types.

   go
   type Reader interface {
       Read(p []byte) (n int, err error)
   }

4. Type Aliases: Introduced in Go 1.9, type aliases are primarily used for code refactoring and allow assigning a new name to an existing type.

   go
   type Bytes = []byte

By utilizing these approaches, you can create custom types tailored to specific requirements, thereby enhancing code structure and clarity.
