Void

Definitions

1. A type (or pseudo-type) indicating the absence of a value. As a function return type, void means the function performs a side effect and returns nothing. In C, 'void*' is a generic pointer that can point to any type. In TypeScript, void signals that a callback's return value will be ignored.

   In plain English: A label that means 'nothing' — used to indicate that a function does its work without giving back a result.

   Example: "The function is void because it just writes to the database — there's nothing meaningful to return."
