Random Internet Lecture: Async Iterables in Javascript
This is a lecture I once prepared and recorded for a job application. I awkwardly removed (most of) the company-specific bits to share with the world. 😄 This lecture is about the Javascript language itself, no extra libraries or tools.
Async Iterables combine the semantic power of async/await (properly rated) with the structure-agnostic pattern of iterables/for...of (totally underrated). This is a one-take lecture about what "for await...of" does and why.
Useful if you want to learn about:
Asynchronicity in Javascript (including some history)
Javascript iterators/iteration protocol (and how to roll your own)
"for await...of" and possible applications of it
Thanks for watching!
