Wes is the man. So easy to follow, doesn’t use unnecessary jargon.

[Maxzilla]

Holy crap, those future APIs look like so much fun!

[mujeexminiminer]

Amazing talk!
Please try and focus more on his slides next time!

[lardosian]

Like this guy, really knows his stuff and is funny also.

[DavidMermelstein]

2nd focusing on slides. Fails the cardinal rule of slide UX.

[anthonytonev]

Why do people hate JavaScript? It's so flexible and expressive nowdays.

Amazing Wes Bos!

[hantuber]

I wish you can see the code while Wes Bos is explaining We're here to learn the contents instead of watching Wes speak...

[angelexi]

Didn't .includes replace .contains?

[Krzysiekoy]

Cool trick with removing certain item from an array (without mutating the array) with slice and spread @20:33 but wouldn't simple .filter() be more convenient and readable?

const newNames = names.filter( name => name !== "lux" )

[nahueljo]

Jeez, you leave the code 10 seconds and then just show him explaining :( I had to go back to the slides like 10 times
He's awesome though, always a pleasure to listen to him

[ashatron]

15:50  "I need an array with 10 slots inside of her"...
Did this abhorrent monster just assume the gender of an Array??

[branquitodemunze]

Cheers for having ugliest colorscheme that he could possibly choose
