create-element.ts

function createElement<T extends keyof HTMLElementTagNameMap>(
  tag: T,
  attrs = {},
  args: string | typeof createElement
  ): HTMLElement {
  const element = document.createElement(tag);

  for (const attr in attrs) {
    element[attr] = attrs[attr];
  }

  Array.from(arguments).slice(2).forEach(
    n => element.appendChild(
        typeof n === 'string' ? this.document.createTextNode(n || '') : n));

  return element;
}
