Node 27’s first alpha jumps from V8 14.6 to 15.6. Practical tip: add the alpha to a non-blocking CI job now. Finding breaking changes in November is cheap. Finding them during the LTS migration is not. #NodeJS #JavaScript #CICD

If you run an End-of-Life Node version, this week’s 16 CVEs are yours forever. No patch is coming. “It still works” is not a support policy. Put runtime upgrades on the roadmap like any other feature. #NodeJS #JavaScript #TechDebt

You click a button... text changes. Color changes. Popup opens.
HOW? 🤯
This is DOM.
Your website is a tree. JavaScript controls it.
Without DOM = poster.
With DOM = alive.
Comment DOM for practice task.

Node just shipped 16 security fixes across 22.x, 24.x and 26.x. One HTTPS bug can leak memory into response bodies, potentially including TLS private keys. Not a “next sprint” upgrade. Patch today. #NodeJS #AppSec #JavaScript

Obsessing over unused dependencies with npx depcheck while your MRR is zero is just avoiding real work. Your 50MB node_modules folder isn't the reason you have no customers.

JS tip: use `Intl` instead of date/number libraries for formatting.
new Intl.NumberFormat("en-US", { style: "currency", currency: "USD" }).format(1234.5)
→ "$1,234.50"

`fetch()` can succeed and still give you a 404.
The promise resolves when the server sends an HTTP error response. Check `response.ok` before treating the result as success, or your UI might try to render the error body as data.

JavaScript `??=` operator:
options.timeout ??= 5000;
Assign only if the value is null or undefined. Perfect for defaults. ✨
