Most "React interview questions" lists online are either trivia (define useEffect) or so advanced they're not useful below 3-4 years of experience. Here are 5 I think are actually worth knowing, with the answer I'd give…
When I started building applications, I used to have a fairly simple definition of success: 𝐈𝐟 𝐢𝐭 𝐰𝐨𝐫𝐤𝐬, 𝐢𝐭'𝐬 𝐰𝐨𝐫𝐤𝐢𝐧𝐠. And honestly, that mindset makes sense when you're learning. You build a feature. You run it. It…
Designing Regulatory-Compliant Synthetic Voice Interfaces for Conversational AI Voice agents powered by ultra-low-latency models (such as OpenAI Realtime API, Cartesia Sonic, and ElevenLabs Turbo v2.5) are…
Hey DEV community! 👋 Have you ever looked at lottery numbers and thought, "There has to be a better mathematical approach than just pure Math.random()?" I did. Instead of leaving everything to blind chaos, I wanted to…
Digital marketing tailored for manufacturing focuses on connecting B2B manufacturers, OEMs, and industrial suppliers with procurement decision-makers, engineers, and plant managers. Unlike consumer-focused marketing,…
Here is a pattern that shows up in almost every codebase: const lastActive = [...users].reverse().find(u => u.status === 'active'); It works. But it creates a full copy of the array, reverses that copy in place, and…
There’s no shortage of new JavaScript projects, but only a fraction deserve a permanent spot in your bookmarks. This week’s selection includes fresh framework releases, interesting React experiments, useful UI…
You've probably been here: you want Jalali dates in the UI, but not a pile of packages, Moment plugins, and Jalali strings leaking into your API. jalali-js (currently 0.4.2) is the small toolkit I reach for in that…
Repeating a YouTube search query three times and keeping only results that appear in two or more of those fetches is more reliable than treating any single fetch as ground truth. The Jaccard similarity between two…
When I added a Traditional/Simplified Chinese converter to my little text-tools site, I assumed it'd be the easy one — swap a few thousand characters for their counterparts and call it done, same idea as the Unicode…
JavaScript Design Patterns: Singleton and Factory Explained with Real Examples When developing software, we often face the same types of problems repeatedly. For example: How should we create objects? Should every part…
A few months ago I noticed something that bugged me enough to eventually write a book about it. AI coding tools are genuinely good now. Copilot, Claude, Cursor — you can describe a feature and watch working code appear…
In a typical TypeScript monorepo, linting alone can eat 45 seconds off every CI run, and that's before Prettier gets a turn. According to a 2026 linting comparison on dev.to, running ESLint across 10,000 files takes…
Disclosure up front: I build Mailward, a browser-based PST/OST/OLM/MBOX/EML viewer. These are the implementation notes. A PST file is not a folder of emails. It is a single-file B-tree database — Microsoft documents the…
Hi everyone, I want to share Block Engine v2.2.0, an open-source polyglot multi-runtime execution engine designed to eliminate the friction of combining multiple programming languages in software development. 💡 Why…
Generative AI platforms are moving beyond static text-to-image outputs toward unified multimodal pipelines that handle image, video, and audio synthesis in a single web interface. A notable implementation in this space…
