## project-1
use the previous learning to build a project where it has topics like fetch data and show and hide components and passing of props

App.js
```
import React, { useState, useEffect } from 'react'
import Loading from './Loading'
import Tours from './Tours'
import './App.css';

// I SWITCHED TO PERMANENT DOMAIN
const url = 'https://course-api.com/react-tours-project'

function App() {
  const [loading,setLoading]=useState(true)
  const [tours,setTours]=useState([])
  
  
  const fetchTours=async()=>{
    setLoading(true)
    try{
       const response=await fetch(url);
       const tours=await response.json();
       setLoading(false)
       setTours(tours)
       console.log(tours)
      }catch(error)
      {
        setLoading(false)
        console.log(error)
      }  
  }

   useEffect(()=>{
    fetchTours()
  },[])
    const removeTour=(id)=>{
    const newTours=tours.filter((tour)=> tour.id!==id)
    setTours(newTours)
  }

  if(loading){
    return(
      <main>
        <Loading/>
      </main>

    if(tours.length===0){
    return(
      <main>
        <div className='title'>
          <h2>no tours left</h2>
          <button className="btn" onClick={ fetchTours}>refresh</button>
