API
The Fetch API in browsers is for makingHTTP requests. It's promise-based and cleaner thanXMLHttpRequest. You can usefetch()
with a URL and options to get data. Returns a promise with a Response object. Extract data with methods like.json()
.
Example Code (Not a part of explanation)
// Fetching data from a URLfetch('https://api.example.com/data').then(response=>{// Check if response is successfulif(!response.ok){thrownewError('Network response was not ok');}// Extract JSON data from responsereturnresponse.json();}).then(data=>{// Work with the retrieved dataconsole.log(data);}).catch(error=>{// Handle any errors that occur during the fetch operationconsole.error('Fetch error:',error);});
