Check out tomdn.com. I created it to make it easier to get to MDN. E.g., instead of googling array.map, just type tomdn.com?array.map. It will take you straight to MDN docs on Array.prototype.map. Other things work as well, like tomdn.com?object.keys, tomdn.com?css.color, tomdn.com?htmlel.button, etc.
If there is a pattern it doesn't recognize, you end up on the MDN search results page.
