This Saturday at meet.js Summit our Kuba Strojewski will give a speech. As usual he's going to be mysterious at first but then he'll lift the fog on the topic of monads in JavaScript. Kuba's talk will provide you with new tools in your repertoire.
In Kuba's own words:
12:15 [track 1 // main auditorium] Awesomely descriptive JavaScript with monads
meet.js Summit is sold-out unfortunately but you may want to check out Kuba's post about Monads on tech.evojam.com.
