  @example //esnext
  import { createElement, append, removeAttr } from 'chirashi'
  const maki = createElement('.maki')
  append(document.body, maki)
  append(maki, ['.salmon[data-fish="salmon"]', '.cheese[data-cheese="cream"]']) //returns: <div class="maki"><div class="salmon" data-fish="salmon"></div><div class="cheese" data-cheese="cream"></div></div>
  removeAttr('.salmon', 'data-fish') //returns: [<div class="salmon"></div>]
  @example //es5
  var maki = Chirashi.createElement('.maki')
  Chirashi.append(document.body, maki)
  Chirashi.append(maki, ['.salmon[data-fish="salmon"]', '.cheese[data-cheese="cream"]']) //returns: <div class="maki"><div class="salmon" data-fish="salmon"></div><div class="cheese" data-cheese="cream"></div></div>
  Chirashi.removeAttr('.salmon', 'data-fish') //returns: [<div class="salmon"></div>]
