How does redux.compose work?

redux.compose is a higher-order function that takes one or more functions as arguments and returns a new function that applies each of the given functions from right to left, passing the result of each function call as the argument to the next. This allows the creation of a new function that represents the composition of several smaller functions.

import { createStore, applyMiddleware, compose } from "redux";
import thunk from "redux-thunk";
import rootReducer from "./reducers";

const initialState = {};

const middleware = [thunk];

const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
const store = createStore(
  rootReducer,
  initialState,
  composeEnhancers(applyMiddleware(...middleware))
);

In this example, redux.compose is used to apply middleware to a Redux store, allowing developers to write reusable middleware chains. The composeEnhancers function is used to enable Redux DevTools in development environments, and to chain together middleware functions using the applyMiddleware function.
