// Custom useFetch hook using async await try catch block
import { useEffect, useState } from "react";
export const useFetch = (url) => {
  const [jsonData, setJsonData] = useState(null);
  const [isjsonLoading, setIsJsonLoading] = useState(true);
  const [fetchError, setFetchError] = useState(null);

  useEffect(() => {
    const abortCont = new AbortController();

    // async await try catch block
    const fetchData = async () => {
      try {
        const res = await fetch(url, { signal: abortCont.signal });
        if (!res.ok) {
          const err = res.status;
          throw new Error(err);
        } else {
