React useReducer hook

Jose Romero

reacthookuseReducer•••

An alternative to useState. Accepts a reducer of type (state, action) => newState, and returns the current state paired with a dispatch method. (If you’re familiar with Redux, you already know how this works.)

Library: react

Shortcut: react.hook.reducer.use

import { useReducer } from "react";

const [state, dispatch] = useReducer(reducer, initialArg, init);
