What is the purpose of the init function in a Go package?
- It's used to declare package-level variables.
- It's the entry point for a Go program.
- It's executed when a package is imported.
- It initializes the main function.
The init function in Go is automatically executed when a package is imported. This makes it suitable for performing package-level initialization tasks, such as setting up global variables, establishing database connections, or registering components. It does not serve as the entry point for a Go program; instead, the main function fulfills that role. The init function is an essential part of package design, ensuring that necessary setup tasks are performed when a package is used.
