pop/src/createElement.js

Pop is a [Hyperapp](https://github.com/hyperapp/hyperapp) / [Ultradom](https://github.com/ultradom/ultradom) spin-off project — yet another micro-framework for creating graphical user interfaces. This is not the final title, but let's go with that for now

import { updateAttribute } from "./updateAttribute"

export function createElement(node, lifecycle, isSVG) {
  var element =
    typeof node === "string" || typeof node === "number"
      ? document.createTextNode(node)
      : (isSVG = isSVG || node.nodeName === "svg")
        ? document.createElementNS("http://www.w3.org/2000/svg", node.nodeName)
        : document.createElement(node.nodeName)

  var attributes = node.attributes
  if (attributes) {
    if (attributes.oncreate) {
      lifecycle.push(function() {
        attributes.oncreate(element)
      })
    }

    for (var i = 0; i < node.children.length; i++) {
      element.appendChild(createElement(node.children[i], lifecycle, isSVG))
    }

    for (var name in attributes) {
      updateAttribute(element, name, attributes[name], null, isSVG)
    }
  }

  return element
}
