JavaScript Performance: 8 Fixes That Actually Matter (2026)Not all optimizations are worth your time. These 8 are. The Hierarchy of PerformanceBefore optimizing, ask:1. Is anyone actually complaining about speed?2. Have you measured where the slowdown is?3. Is this optimization worth the complexity?Rule of thumb: Optimize the hot path first.

Why I Built All 170 Tools to Run in the Browser (And What I Learned)

Why I Built All 170 Tools to Run in the BrowserWhen I started building UtilVox, the obvious approach was server-side processing. Upload file → process on server → return result. Every major tool site works this way.I went the opposite direction. Here's why — and what I learned. The Problem With Server-Side Tool SitesMost free online tools have a dirty secret:Your files go to their servers.When you "compress" a PDF on a popular site, that file travels to their infrastructure, gets proc

From Repetition to Reusability: Custom Hooks in React

IntroductionWhen I started learning React, everything looked simple. Creating components, using useState, and handling events felt easy. But as I started building more applications, I noticed one problem again and again — I was repeating the same logic in different components.For example, fetching data, handling inputs, managing loading states — these things were written multiple times. At first, I ignored it. But later, the code became confusing and harder to maintain.That is when I learn

React Hooks

I Replaced a Polling Loop With Three React Hooks and a Firestore Rule

The first version of the VORTEX dashboard polled an API endpoint every five seconds. It worked. It also meant the UI was always up to four seconds behind reality, and every agent write to Firestore required a separate read path just to surface it on screen. I replaced the whole thing with three custom hooks and onSnapshot listeners. The dashboard has been real-time since, with no polling, no message queue, and no separate read model. The Data Model FirstBefore writing a single hook, I mappe

AI will keep React alive forever. That should terrify you.

Whenever you tell an AI, “build me a login page,” it writes React. Not Svelte. Not Solid. Not Vue. React. And that default is unobtrusively but strongly shaping the future of the web as a whole.I've been mulling this over since I came across the Dead Framework Theory. The argument is simple and uncomfortable: LLMs are trained on massive amounts of existing code, and React dominates that training data by a landslide. AI generates React code. Humans integrate that React code and ship it. It's now
