A Fetch API Example
The example below fetches a file and displays the content:

Example

fetch(file).then(x => x.text()).then(y => myDisplay(y));

Since Fetch is based on async and await, the example above might be easier to understand like this:

Example

async function getText(file) {
  let x = await fetch(file);
  let y = await x.text();
  myDisplay(y);
}


Try it Yourself »

Or even better: Use understandable names instead of x and y:

Example

async function getText(file) {
  let myObject = await fetch(file);
  let myText = await myObject.text();
  myDisplay(myText);
}

Letztens wollte ich einfach mal mein Glück testen, weil ich neugierig war. Ich suchte ein unkompliziertes Online-Casino. https://ivybet.ch hat viele Slots und attraktive Boni speziell für Schweizer Spieler. Die Seite ist einfach zu bedienen. Mir gefällt besonders die Übersichtlichkeit und die schnellen Ladezeiten.

The Fetch API is indeed a powerful tool for making HTTP requests effortlessly. It's great to see how it simplifies the process compared to XMLHttpRequest. For those in Korea looking to explore online opportunities, especially in gaming, I found that there are platforms that offer fantastic bonuses specifically for Korean residents. One such site is https://sk-win.kr, which has a wide range of games and appealing promotions. It's worth checking out if you're interested in a seamless experience tailored for players in Korea. Happy coding and gaming!
