I use the Personal Blocklist app in Google Chrome to block w3schools.com results. Additionally, I saw http://mdn.io http://mdn.io website surfacing in the internet recently. I use mdn.io to get redirected to MDN without doing a Google Search. Examples: http://mdn.io/parseint http://mdn.io/parseint http://mdn.io/window http://mdn.io/window http://mdn.io/math http://mdn.io/math
