Like an array, Observable has a map method that allows us to transform a sequence into a new Observable.

Really great series - I'm learning a terrific amount. I've known about filters/maps etc but never really quite understood their true value.

On thing tho, in the video above you comment out code to show that observables are lazy. But you comment out the alert too so of course nothing happens - lazy or not.... Took me a while to realise what I was supposed to (not) see :)

Thanks for pointing that out. Sorry about that.
