https://developer.mozilla.org/zh-CN/docs/Web/API/Document/createComment

createComment() 方法用来创建并返回一个注释节点.

var commentNode = document.createComment('注释')

document.querySelector('body').appendChild(commentNode)

api 是在看 snabbdom 源码的时候发现的

// init.ts

const sel = vnode.sel;
if (sel === "!") {
  if (isUndef(vnode.text)) {
    vnode.text = "";
  }
  vnode.elm = api.createComment(vnode.text!);
}

h("!", "注释"),
