Do not yield to javascript generators! #109

Closed BrunoGodefroy closed 6 years ago

BrunoGodefroy commented 6 years ago

Abstract Have you ever found yourself completely lost in front of a yield statement? What is this? Where does my promise go? How come I get the result back?

Generators are widely used amoung Node and javascript libraries to enable developers to write powerful code in a simple way.

I will try to answer all these questions and we will recreate together the co library that is used, for example, in Koajs.

I would then like to go into a step by step decomposition of redux-saga to understand how this wonderful library uses generators.

A bit about me I'm a full stack developer at Theodo UK, a web agency in central London. We help our clients to solve their business problems through code. Our clients range from young startups to large corporates. Twitter: @switcher7707

Hi Bruno,

First of all, thank you for your proposal!

I have a few questions / suggestions if you don't mind:

Our audience consists of a wide variety of developers and tech enthusiasts. If you would like to provide really good value it maybe better to do a focused and slower paced talk on either generators in general or on redux-saga only. Obviously, redux-saga could still include explanation of generators but I feel like introducing generators, reimplementing co, dissecting saga and everything around it might take a lot longer than planned.

Also, would 23rd of August be suitable for you?

admataz commented 6 years ago

Hi Bruno, this is great - thank you... and great advice from @lazlojuly. I agree - keeping it focused will help you fit everything in.

BrunoGodefroy commented 6 years ago

@lazlojuly @admataz The 23rd of August is perfect for me!

I have already given this talk in front of my colleagues at Theodo UK. The talk lasted around 40 minutes and I had pretty good feedbacks: a lot of them were surprised about how easy it is to rewrite co.

I was planning to do a live coding that is indeed very similar to what Mattias did on his channel. My implementation is a bit different but the idea of the live coding is the same.

I can of course drop the last part to make the talk a little shorter and easier to follow, how long should I aim for?

lazlojuly commented 6 years ago

@BrunoGodefroy 20-25 minutes with easy to follow pace.

I booked you in for 23rd. I am looking forward to this! Thanks!

admataz commented 6 years ago

thanks @lazlojuly. could you run a build and push an update to the website so this gets published there? otherwise i'm on the move till this evening and can do it then.

admataz commented 6 years ago

Hi @BrunoGodefroy
I hope you're well? Just confirming... all good for your talk this Wednesday?

BrunoGodefroy commented 6 years ago

Hi @admataz Yes everything is good for my talk! At what time should I arrive? 6:30pm?

admataz commented 6 years ago

Great - thanks @BrunoGodefroy - yes 6:30 will be great

BrunoGodefroy commented 6 years ago

Ok see you there!

admataz commented 6 years ago

Hi @BrunoGodefroy - thanks for a great talk last night - and for coming along and sharing your knowledge. All the feedback I had has been very positive - and people were very impressed with your live coding bravery! I'll let you know when the video is ready and online. Hopefully see you back at LNUG soon! Best, Adam
