Continuations

Continuations are a programming concept that captures what a program is doing at a specific point, allowing it to pause and later resume exactly where it left off. Think of them as a bookmark or checkpoint that remembers the current state of a process, including pending actions or context. This mechanism makes it easier to manage complex tasks like asynchronous operations, user interactions, or complex control flows, because the program can effectively "save" its place and continue later without losing progress or structure.
