Demo:

// First you should creating the store.
// Usually you will create one store for each app and share this variable.
// Usually you will put this in separate file.
import {NewStore} from "globux"

const store = NewStore({
  key1:0,
  key2:0,
})



function App(){
  // This component will automatically re-render when store.key1 will change.
  store.useRerenderIfChange(()=>[store.key1])
  function incrementKey1(){
    store.key1++
    store.updateStore() // This will check which component should re-render since the last update.
  }
  return <div onClick={incrementKey1}>
    Store key1: {store.key1}
    <ChildComponent />
    </div>
}

function ChildComponent() {
  // This component will automatically re-render when store.key2 or store.key1 will change.
  store.useRerenderIfChange(()=>[store.key2,store.key1])
  function incrementKey2(){
    store.key2++
    store.updateStore()
  }
  return <div onClick={incrementKey2}>
    Store key1: {store.key1}
    Store key2: {store.key2}
    </div>
}
