This has serious potential for the entire JavaScript ecosystem to finally bring everything under a unified umbrella, to bolster backend/server-side engineering. This is a definite win-win for everyone in the ecosystem.

In 2022, Igalia helped establish WinterCG, which aimed to establish interoperability across server-side runtimes, as well as with the web. Now, this group moves to Ecma, becoming WinterTC, with our own @andreubotella.com as co-chair alongside Deno's @lcas.dev www.igalia.com/2025/01/10/W...

Deno is committed to web standards - that's why we co-founded WinterCG two years ago. Today marks the next step in that journey: WinterCG moves to Ecma International as technical comittee 55 (TC55). Goodbye WinterCG, welcome WinterTC! deno.com/blog/wintertc
