What is the purpose of init functions in Go?

In Go, the `init` function is a special function that is automatically executed before the main function, allowing for initialization logic to be executed without explicitly calling it. This function is typically used to set up initial configurations, default values, or perform setup tasks that need to run before the rest of the program. Each package can have its own `init` function, and they are executed in the order of dependency resolution of the packages.

Example

// Example of init function in Go package main import "fmt" func init() { fmt.Println("This is the init function!") } func main() { fmt.Println("This is the main function.") }
