effection with Charles Lowell | TypeScript Showcase #7
Effection gives you some core primitives to write concurrent code. It's got some super well-thought out core primitives that enable you to do some pretty amazing things! In this showcase we'll see lots of code but also talk lots of theory on how all this stuff works. Really hope you enjoy this one! Let us know what you think.

Eric Bower is a software engineer working out of Ann Arbor, Michigan. When he's not running/longboarding/building keyboards/spending time with family, he likes to push the boundaries of TypeScript, particularly when it comes to utilizing generators. He's worked on redux-saga and is the creator of starfx. You might know him for his project https://neovimcraft.com, or maybe you've seen his blog (https://bower.sh ) come up on Hacker News.
