Element.remove() is unsupported in Internet Explorer

While testing 8.0-beta in IE11 I’ve run into a problem in unmountComponent() calling .remove() on base:

https://github.com/developit/preact/blob/8/src/vdom/component.js#L266

Changing that line to:

base.parentNode.removeChild(base);

…fixes the problem. I’m not sure if 8.0 is supposed to support IE, but worth keeping in mind.

I’m pretty sure IE8 never was supported by Preact. React does support it though.

If anyone’s trying to work around this problem, you can apply a minimum polyfill for the required methods:

(function() {
  function remove() { this.parentNode && this.parentNode.removeChild(this); }
  if (!Element.prototype.remove) Element.prototype.remove = remove;
  if (Text && !Text.prototype.remove) Text.prototype.remove = remove;
})();
