TypeScript 6.0 RC and Solid 2.0 beta arrive

Tue, 10 Mar 2026 00:00:00 +0000

#776 — March 10, 2026

JavaScript Weekly

Solid v2.0.0 Beta: The <Suspense> is Over — After a long experimental phase, Solid 2.0’s first beta lands with first-class async support where computations can return Promises or async iterables, and the reactive graph suspends and resumes around them natively. <Suspense> is retired in favor of <Loading> for initial renders, and mutations get a first-class action() primitive with optimistic support. For existing users the breaking changes are substantial, but there’s a migration guide.

Ryan Carniato

💡 Ryan also had an AI write up the architectural case for Solid 2.0, framing fine-grained reactivity as the only sustainable model for an AI-agent world. He also did ▶️ a livestream where he tried to break Solid 2.0 by pushing against its limits.

TypeScript 6.0 Release Candidate — v6.0 is primarily a stepping stone to the eventual Go-powered native TypeScript 7.0 due later this year and all the necessary tsconfig.json changes will put you in a good position for the future. There are only a few small changes in the RC vs the recent beta.
