Building React Components: From JSX to Production-Ready Code
TL;DR: React components are reusable UI building blocks that combine structure, logic, and styling in isolated modules. Function components with Hooks are now the standard, replacing classes for cleaner, more maintainable code that scales across modern frameworks.React components form the backbone of every React application. They break your user interface into small, logical pieces that handle their own structure, styling, and behavior independently. This modular approach transforms how develope

How to Stop Worrying About AI Taking Your Frontend Job (And What to Build Instead) published:
If you are a junior developer or currently learning web development, the market feels incredibly intimidating right now. Everyone keeps saying "AI is going to replace developers," and generic React/HTML portfolio sites just aren't impressing recruiters anymore. The truth is, AI won't replace you, but a developer who knows how to build AI-powered applications will. If you want to move past basic landing pages and build things that actually prove you are a modern developer, here is the exact 3-ste
Why Your API Calls Break: A Developer's Guide to URL Encoding
Why Your API Calls Break: A Developer's Guide to URL EncodingURL encoding is one of those things that seems trivial until it isn't. You fire off an API call, the server returns a 400, and you stare at the URL wondering what went wrong. Nine times out of ten, the answer is encoding.Here are the three URL encoding mistakes that cost developers hours of debugging — and how to fix them in 30 seconds. 1. The Double-Encoding TrapThis is the most insidious bug. You encode a URL once, pass it
A First Look at Scroll-Triggered Animations
Chrome has shipped scroll-triggered animations, and is the first browser to do so. If you update to Chrome 146, you can view the demo below, where the background of a square fades in over the duration of 300ms, but only once the whole element is within the viewport.CodePen Embed FallbackThis is a bit different to how scroll-driven animations work, so in this article I’ll compare them, and then show you how scroll-triggered animations work.Scroll-triggered animations vs. scroll-driven animationsS
use client vs use server in Next.js: The Real Difference
If you think "use client" and "use server" are opposites — one for client components, one for server components — you have the single most common App Router misconception. They are not symmetric.

Browser APIs - the whole ocean of features to build apps
Your browser ships somewhere between 350 and 450 APIs (depending on the browser). Most developers reach for the same dozen. There's an ocean of platform features sitting unused.The web platform is enormous. We just keep treating it like a phone book. ProblemHow to know what you need? MDN is nice but it's just a catalog. Most of a time you need to know what to look for. caniuse is per-feature, web.dev is article-driven. Nothing gives you the map.What I wanted was a map - a single picture of
