reducer

Makes things smaller

A reducer is something that reduces—makes smaller, lessens, or diminishes.

In cooking, a reducer concentrates flavors by boiling liquid down.

In plumbing, a reducer is a fitting that connects pipes of different diameters.

In programming, particularly with state management libraries, a reducer is a function that takes a previous state and an action, then returns a new state: The reducer handles all the cart updates.
