Reviewer scorecard
“Deno 2's Node.js compatibility changes everything. Secure by default, great tooling, and now practical for real projects.”
“Typed errors and dependency injection for TypeScript done right. The platform modules (HTTP, Schema, SQL) are production-grade.”
“Deno 2 finally delivers on the promise. npm compatibility means you can actually use it without friction.”
“Steep learning curve and the functional programming style isn't for everyone. The benefits are real but the adoption cost is high.”
“Security-first runtime design is correct for the AI era where you're running untrusted code. Deno Deploy is compelling.”
“Effect brings Scala/Haskell-level reliability to TypeScript. As TypeScript applications grow in complexity, Effect becomes more valuable.”
