JavaScriptでfetchを使う方法

fetch(url)
  .then((response) => response.text())
  .then((text) => console.log(text))
  .catch((error) => console.log(error));

fetch('http://example.com/movies.json')
  .then(function(response) {
    return response.json();
  })
  .then(function(myJson) {
    console.log(JSON.stringify(myJson));
  });
