Flash-forwards and flashbacks are similar literary devices in that they both move the narrative from the present to another time. The difference is that while a flash-forward takes a narrative forward in time, a flashback goes back in time, often to before the narrative began.

What is the difference between flashback and flashforward?

Flashbacks are often used to recount events that happened before the story's primary sequence of events to fill in crucial backstory. In the opposite direction, a flashforward (or prolepsis) reveals events that will occur in the future.

Is Flashforward same as foreshadowing?

The main difference between flash forward and foreshadowing is that in flash forward, the plot jumps ahead to the future of the narrative whereas, in foreshadowing, the author drops subtle hints and clues about the plot developments to come later in the story.
