I knew about this a while ago, I guess when it first popped up. But until recently had forgotten about it. After all, the google is pretty easy to get to no matter where you are. But there may be those times when you know what you want is in the mozilla docs, or just expect to find what you want there, and for those times you can use the “I’m feeling lucky” mozilla docs url: mdn.io/<what you're looking for>
. Examples:
http://mdn.io/let
http://mdn.io/setImmediate
http://mdn.io/Array.slice
http://mdn.io/String.slice
Here’s the github repo for it: https://github.com/lazd/mdn.io
I thought it was a good idea, and MDN is one of the better resources (if not the best) out there.
