The Miracle of Generators #46

Closed bodil closed 8 years ago

bodil commented 8 years ago

The ECMAScript 2015 specification introduced iterators, which generalise iteration over common data structures, as well as providing an interface for allowing you to iterate over any custom data structures using common language constructs. ES2015 also introduced generator functions, which make writing arbitrary iterators a lot easier and less boilerplatey.

But generators aren't just for making simple iterators over data structures. Because they're bidirectional—they don't only produce output, they can also take input—they're actually coroutines, which means there's no end to the sort of fun you can apply them to. We're going to explore how we can use them to make asynchronous programming in JavaScript a lot more elegant—to chart a path out of callback hell. And then we're going to take a look at what we've really discovered: one of the most fearsome mysteries of computer science, suddenly laid bare before us.

Be warned, this is a 40 minute talk.

jkbits1 commented 8 years ago

@bodil I'm keen to hear this

malditogeek commented 8 years ago

Sounds brilliant, I played a bit with Koa and would love hear more about generators :+1:

olizilla commented 8 years ago

Very much :+1:

iancrowther commented 8 years ago

Are you ok for September 23rd?

bodil commented 8 years ago

Definitely.

iancrowther commented 8 years ago

Your on the roster, really looking forward to this one. We have a max speaking slot of 30 mins so if you could condense the 40 mins and push q's onto gitter, that would help us keep the venue happy.

w00t

I'd have to cut the introduction and assume people know their iterators, if so, but I think that wouldn't have a huge impact on the quality of the talk.

iancrowther commented 8 years ago

the audience is very technical so its safe to assume they are up to date.

iancrowther commented 8 years ago

@bodil do you want to go on 2nd or 3rd?

bodil commented 8 years ago

3rd, for preference.

iancrowther commented 8 years ago

done.. do you have screen recording software? if not can you full-screen record via quicktime for the youtube vids

bodil commented 8 years ago

I'm on a Chromebook, so it'll be... experimental... but we can give it a go. There is software for recording browser tabs, which is what I'll be presenting from, so in theory it should work.

ok cool - good job I mentioned it then hey :-)
