//AJAX XHR

function reqListener(response){
    let data = response.responseText;
    let json = JSON.parse(data)
    console.log('Fetched data: ', data)
    console.log('is woorking!!!')
}


let xhr = new XMLHttpRequest()
xhr.addEventListener('load', reqListener)
xhr.onerror = console.error()
xhr.open('GET', 'https://jsonplaceholder.typicode.com/posts/1')
xhr.addEventListener('error', function(err){
