So...a joke with a colleague at work got a little bit out of hand. I wrote a 4-Bit Virtual Machine in @typescript, using just Types, no JavaScript.

Here's why the Records and Tuples proposal died, and how Composites might solve it.
I did my homework for this one - I interviewed @acutmore, the Composites TC39 champion. And I'm really proud of how it turned out.
I'd love any feedback you can give me, and I'll make any necessary adjustments before it goes live.
My talk on ts-blank-space is now online (35min)

Today, I'm releasing a TypeScript compiler called ts-blank-space 🎈
We use this at @TechAtBloomberg to perform type-stripping on a modern subset of TypeScript.
It's written in TypeScript and is fast because it uses whitespace to enable work-skipping.

For our use case, ts-blank-space works great.
I'm also impressed @kdy1dev was able to adopt this approach so quickly in SWC.
Let me know what you think and please raise any issues you find on the repo!

I thought the "just JavaScript" part of React was: there isn't new syntax for `if` and loops within the template (JSX). Any logical aspect should be achieved with "just JavaScript"
Test fixtures for code transforms containing things I can't un-see
ALT A TypeScript if statement but without brackets that appears to have two statements in its body but the first is a type declaration and there are also no semicolons. function f3(): void { if (true) type foo = string console.log('f3' as foo) }

ECMAScript explanations 😉
The annual treatment returns with @marypcbuk thoroughly delving into the details of @TC39's ES2024 new JS language features 🎉
Contains commentary from @littledan @acutmore and myself.

@poteto I was looking at the react compiler playground and started wondering:
Has there been research into trying to avoid props diffing too?
i.e when a inner element memo slot is invalidated all the parent jsx is re-created. Even if the non-children props are static.

Walked in with @acutmore this morning. The company was delightful. The weather..... was British

After spending a week going through the new errors when checking with TypeScript 5.4.
My biggest take away is: in many cases an explicit type annotation, especially at module boundaries, would have made my task much easier 😎
The TypeScript tooling used by @TechAtBloomberg checks our internal package ecosystem to identify breaking changes in new versions of TypeScript.
We check each major release & publish a report.
Thanks to @acutmore for reviewing TS 5.4 Beta 👍
