// i expect to return an array of arrays [[],[]]. // but i get array on undefineds [undefined , undefined]

Also when i want to work with useState hook and set the state on every element in the array But i get the initial value. I did some search on useState and i think it is not re-render on the same event and i have to do another trigger in order to get the current state. // please someone help me acheive what i want to do. // also help me understand how to get the current state in useState immediately after changing it (on the same click).

  const [favSchemas, setFavSchemas] = useState([]);
