+/**
+ * Creates a store enhancer that applies middleware to the dispatch method
+ * of the Redux store. This is handy for a variety of tasks, such as expressing
+ * asynchronous actions in a concise manner, or logging every action payload.
+ *
+ * See `redux-thunk` package as an example of the Redux middleware.
+ *
+ * Because middleware is potentially asynchronous, this should be the first
+ * store enhancer in the composition chain.
+ *
+ * Note that each middleware will be given the `dispatch` and `getState` functions
+ * as named arguments.
+ *
+ * @param {...Function} middlewares The middleware chain to be applied.
+ * @returns {Function} A store enhancer applying the middleware.
