Here's Node.js running a web server, in an iframe, in a browser tab, in a terminal-based browser, in a terminal tab, on a laptop.

#WebContainers are pretty cool :)

#Deno 2.0 previewed at #SeattleJSConf. See livestream here: https://youtu.be/Dkqs8Mcxbvo?t=424

Today Kevin Whinnery of the #Deno team previewed Deno 2.0 at #seattlejsconf that will include a Deno Package Registry!

Josh defines compiler as a transpiler which runs a type checker, which I don't think is what most people would expect, but neatly solves a lot of js diction disagreements.

#seattlejsconf

Eslint is not good for formatting. Don't use eslint to format your code; prettier is better for formatting. It might be nice to add formatting to eslint, but for now use them in conjunction to do separate but complimentary things.

#seattlejsconf

Josh is recommending we run with --allow-warnings and --report-unused-disable-directives to fail when there are unused disable comments and warnings.

#seattlejsconf

"Never block a local dev server or local build on a linting failure."

Up next is Josh Goldberg with static analysis. I've been struggling with @tseslint recently, so this talk feels like this talk is specifically for me.

"It's time to learn typescript my dudes and dudettes"

kinda disappointed typescript is the strongly-typed compile-to-js language that won, but strong types are better than weak types so 🤷‍♂️

#seattlejsconf

Array methods!
- toSorted
- toReversed
- findLast
- findLastIndex
- toSpliced

#seattlejsconf

Array.at() is now preferred over square brackets for accessing array members.

#seattlejsconf

Top-level await is the first up -- this allows us to avoid the async anonymous main function necessary to await promises that was required previously.

Here's the slides for my talk:

Any history of js that includes neopets is a good history of js

Up next is Christina Zhu talking about ES13

Loving the mastodon shout from @monteslu #seattlejsconf

We're learning about https://fidoalliance.org/ who seem to be an organization pushing for better internet security.

#seattlejsconf #infosec

Passwords suffer from the lack of security and human forgetfulness. Passkeys allow humans to login using with their device lock screen.

It's time for the CTA!

- Write a design system
- Start with a style guide if a whole design system is too much
- Learn about the design tokens already present in your system
- Look at the consistency of your design system

#seattlejsconf #designsystems

Design Token naming is so much harder than I expect. AWS Amplify publishes their recommendations here: https://ui.docs.amplify.aws/react-native/theming#design-tokens
