Lodash-like chaining using reduce for Absurdum. Why? Cuz we can..
// Law of Absurd Reduces: Everything that can be implemented with reduce() will eventually be implemented with reduce()
/**
* @param {Object} chainableFunctions object where each key is the name of a function and it's value is the function itself
*/
const createChainables = (chainableFunctions) => ({
chain(initialValue) {
const operations = [];
const evaluate = () => operations.reduce(
(value, [func, ...args]) => func(value, ...args),

Zustand state manager usage
import create, { State, StateSelector } from 'zustand';
// initialization
const initialStates = { count: 0 }; // no need to add your actions here like how zustand README shows.
const useStore = create(() => initialStates);
const { getState, setState } = useStore;
// usage within function component (reactive)
const Component = () => {
const count = useStore(state => state.count);
