A Request is built of an input (URL) and options.

Make a GET request:

js
fetch('https://example.com/').then(callback);

Make a application/json POST request:

js
const url = 'https://example.com/';
const options = {
    headers: { 'Content-Type': 'application/json' },
    method: 'POST',
    body: JSON.stringify({ username: 'example' }),
};
fetch(url, options).then(callback);

Response ​

A Response object is returned.

js
fetch('https://example.com/').then((res) => {
  console.log(res.status);
  res.text().then((text) => console.log(text));
  if (!res.ok) {
    throw new Error('HTTP request failed');
  }
});
