If the value of the expression following the await operator is not a Promise, it's converted to a resolved Promise.async await js
fetch('coffee.jpg')
.then(response => {
if (!response.ok) {
throw new Error(`HTTP error! status: ${response.status}`);
} else {
return response.blob();
}
})
.then(myBlob => {
let objectURL = URL.createObjectURL(myBlob);
let image = document.createElement('img');
image.src = objectURL;
document.body.appendChild(image);
})
.catch(e => {
console.log('There has been a problem with your fetch operation: ' + e.message);
});await javascript
The await operator is used to wait for a Promise. It can only be used inside an async function within regular JavaScript code; however it can be used on its own with JavaScript modules.Copyright © 2021 Codeinu
