I'm kind of shocked that you didn't highlight the webtransport / quic stuff that made it into this release. Kind of a big deal. First js runtime to support it directly, I think, beating node and bun.

What extension is being used in vscode to guess/assume the type of the value being set on a variable? An example of this is at 27:52 when he writes `export const sidebar =` there are ellipses that appear after `sidebar: ...` <- and then when he assigns an empty array, it goes to `sidebar: never[] =` and then when he adds strings, it switches to `sidebar: string[]`. What is this 'intellisense' magic and is it actually adding the strong typing to the code or just syntax sugar for the developer's benefit to remind them to strong type their variable declaration?

it would be cool if you guys would implement something like bun s3

The import system is still a mess and only works for esm typescript modules.
5 different ways to import type declarations (2 of which are already deprecated) for js modules.
No "file:" import for local modules.
Module caching problems.

Deno should replace nodejs crap globally. Will that happen? Not anytime soon.

The only reasons I haven't used deno is because of its high memory usage, is there any good news about this?

The moderator should stop "mmh!" confirming everything the speakers say. It's annoying to the audience. Any moderator should understand the speakers aren't speaking to him but to the audience. A moderator's job is to facilitate speakers to talk to the audience and then get out of the way, not in the way.
