Question: Compare Node.js 22 and Node.js 24.

Answer:

Node.js 22 and Node.js 24 are both even-numbered LTS (Long-Term Support) releases, with Node.js 22 being the previous stable LTS (released ~April 2024) and Node.js 24 becoming the current LTS in October 2025 (released May 2025, LTS from ~October 2025 to April 2028).

Node.js 24 brings meaningful improvements in performance (in most cases), modern JavaScript features, security defaults, and developer experience, while introducing several breaking changes that require attention during migration.

Key Comparison Table

Aspect Node.js 22 Node.js 24 Winner / Notes
Release & Support LTS (Active until ~April 2026) LTS (Active until April 2028) Node.js 24 (longer remaining support)
V8 Engine V8 12.4 V8 13.6 Node.js 24 (newer JS features + perf)
Performance Solid baseline Often 15–30% faster in general JS/HTTP workloads; some native addon cases (e.g. SQLite) show regressions Node.js 24 in most cases, regressions possible
Built-in fetch Available (Undici-based) Undici 7.0 → better HTTP/2, HTTP/3, connection pooling, performance Node.js 24
Test Runner Stable Stable + more defaults & improvements Node.js 24 (mature)
Permission Model Experimental Stable (--allow-* flags for fs, net, etc.) Node.js 24 (production-ready security)
OpenSSL 3.0 / 3.x series OpenSSL 3.5 (default security level 2) Node.js 24 (stricter crypto defaults)
New JS Features ES2024-ish Float16Array, Error.isError, global URLPattern, explicit resource management (using), more Node.js 24
npm npm 10 npm 11 (perf + security improvements) Node.js 24
Breaking Changes — Stricter fetch/AbortSignal, Buffer behavior, Windows path fixes, stream/pipe errors now throw, crypto changes Node.js 22 (fewer migration issues)
Recommended for prod Safe & conservative choice in early 2026 Current LTS recommendation (as of Feb 2026) Node.js 24 (current best LTS)

Main Advantages of Upgrading to Node.js 24

  • Longer support horizon.
  • Better general runtime performance and memory usage (thanks to V8 13.6).
  • Production-ready security features (stable permissions model, stricter OpenSSL defaults).
  • Modern web platform alignment (enhanced fetch, global URLPattern, newer typed arrays).
  • Future-proofing (most new ecosystem libraries will target recent Node versions).

Potential Downsides / Migration Considerations

  • Several breaking changes (detailed in the official v22 → v24 migration guide).
  • Rare performance regressions in specific native modules / addons (e.g. certain SQLite bindings).
  • Need to test stricter validation and crypto behavior.

Overall, as of February 2026, Node.js 24 is the recommended version for most new projects and for upgrading production workloads from Node.js 22, provided you handle the migration steps.
