If you need a higher data rate then a different sensor could be an alternative.
The DHT22 is not state-of-the-art anymore (proprietary protocol, power consumption, low temperature accuracy, no heating support to prevent condensation). It was one of the first affordable humidity sensors but today there are many better alternatives with Espruino support (SHT2x, SHT3x, HTU21D, BME280, ..).
One of the cheapest is the HTU21D/SHT21: http://www.ebay.com/itm/112049178633
