有许多使用Mime类型text/javascript、application/json、image/...等的blob的用例示例
MDN Bolob（）示例还显示：

const array = ['<q id="a"><span id="b">hey!</span></q>']; // an array consisting of a single string
const blob = new Blob(array, { type: "text/html" }); // the blob

上面的例子包含一个HTML片段？

• 它可以以任何方式附加到DOM中吗（作为Blob或在获得对象URL之后）？
• （请提供代码片段示例以展示用例。）*
  ********************重点特别放在上述用例上。

更新

根据Bergi的要求：

Blob {type: "text/javascript"}用例

// import module
(async () => {

  const response = await fetch('module url');
  const blob = await response.blob(); 
  // Blob { size: 10176, type: "text/javascript" }
  const url = URL.createObjectURL(blob);
  const obj = import(url);

})();

Blob {type: "application/json"}用例

以Import Attributes为准

// import JSON
(async () => {

  const blob = new Blob(['{ .... }'], {type: 'application/json'});
  // Blob { size: 10176, type: "application/json" }
  const url = URL.createObjectURL(blob);
  const obj = import(url, {with: {type: 'json'}});
  
})();

Blob {type: "image/..."}用例

// include remote image
(async () => {

  const response = await fetch('image url');
  const blob = await response.blob(); 
  // Blob { size: 10176, type: "image/png" }
  const url = URL.createObjectURL(blob);
  const img = document.createElement('img');
  img.src = objectURL;
  document.body.appendChild(img);

})();
