What is dx in Deno 2.6?

Dx runs npm/JSR binaries like npx, but with Deno prompts, lifecycle scripts, and security flags. Install alias via `deno x --install-alias`.

Is Deno 2.6 faster than previous versions?

Yes, tsgo offers 2x type-checking speed (unstable). V8 14.2 and opts boost runtime too.

Should I switch from Node to Deno now?

Not fully—ecosystem gap persists. Use Deno for security-heavy scripts, stick with Node for legacy.
