How to use parse-entities - 6 common examples

export default function entityPrefixLength (value: string): number {
  /* istanbul ignore if - Currently also tested for at
   * implemention, but we keep it here because that’s
   * proper. */
  if (value.charAt(0) !== '&') {
    return 0
  }

  const prefix = value.split('&', 2).join('&')

  return prefix.length - decode(prefix).length
}

if (position === -1 || position === value.length - 1) {
      return false
    }

    content = content.substr(MAILTO_PROTOCOL.length)
  }

  /* istanbul ignore if - never used (yet) */
  if (silent) {
    return true
  }

  const now = parser.eat.now()

  return parser.eat(subvalue)(
    renderLink(parser, decode(subvalue), content, null, now)
  )
}

dataAttrs.forEach(d => {
      const [key, value] = d.split('=')
      data[
        decodeEntities(key.replace(/^data-/, ''))
