How does Go handle package visibility and encapsulation?

  • All variables and functions in a package are visible and accessible from outside the package.
  • Go uses uppercase initial letters for variables and functions to make them public.
  • Go uses lowercase initial letters for variables and functions to make them private.
  • Go has no concept of package visibility or encapsulation.
Go enforces package-level encapsulation by convention. Variables and functions with uppercase initial letters are considered public and can be accessed from outside the package, while those with lowercase initial letters are considered private and can only be accessed from within the same package. This convention helps maintain code organization and prevents unintended access to package internals, promoting encapsulation and code stability.
