What it is

A JSConf 2014 talk visually breaking down algorithms behind everyday UI patterns, such as dropdown menus that vanish when the mouse drifts and picking the nearest target to the cursor. It shows how these are implemented in JavaScript.

Why Hacker News recommends it

HN links it whenever menu hover problems or nearest-to-pointer selection come up, and as proof algorithms matter in front-end work.
