We've published our official JavaScript SDK on @jsr_io. In Deno, we can use web standard interfaces like WebSocket on the server, as in this example with the Realtime API. Let us know what you think! π¦

It's done. Now itβs your turn, @Oracle.
Weβve submitted a formal petition to cancel the JavaScript trademark: it is generic, Oracle has abandoned it, and Oracle committed fraud on the USPTO during the last trademark renewal.
Oracle has until January 4th to respond, or the case will go into default, which will result in the trademark being canceled.
It's time to #FreeJavaScript.

Some news:
After 7 years, it's time for me to hand in my lanyards, ssh keys, and move on from @Netlify
I'll be leaving in October
I'm incredibly proud of the work done, the friends made, the lessons learned, and Netlify's ongoing mission to build the web
Now.. where next?

zero-install server-side javascript
What if I told you you could run a @tldraw desktop app with just a URL? Well, you can, thanks to @deno_land and an OSS library I'm working on. So stoked to have this working.

TypeScript excitement π
Congrats to @acutmore on releasing a brand new type-stripping compiler: ts-blank-space β¨
β‘οΈ 5.6x faster than tsc due to zero-codegen
π· Written in TS
π― Uses the official TS parser
π― Accurate/preserved source locations
πͺ Battle-tested in production
Today, I'm releasing a TypeScript compiler called ts-blank-space π
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.

Oracle urged again to give up JavaScript trademark dlvr.it/TDKfb6
Luca Casonato π³οΈβπ retweeted
Despite its minimal involvement in the language, @Oracle still owns the #JavaScript trademark. Ryan Dahl and other JS stewards are asking the company to release the name to the public domain. . . thenewstack.io/free-javascri⦠#Opensource

I wrote this open letter because I believe the "JavaScript" trademark has been abandoned by @Oracle as defined in US trademark law. "JavaScript" is a generic term for the world's most popular programming language - not an Oracle product. If you agree, please sign the letter to give weight to this cause.
