I love how easy my life has gotten once I embraced AI IDEs to their full potential. (Agent, Ask, Rules, MCPs) It has its frustrations; I am yelling at it like a madman, but it still increased my productivity 10. Wrote a piece on how I use Cursor: neciudan.dev/cursor-ai-th...

My favorite question to ask in technical interviews: "What's one product or app you truly enjoy using?" I follow up with what feature stands out for you in that product? Then, I ask the candidate how they would design/build that feature if they were in charge.

What I understand from Single Responsibility Principle is not that each component should do one thing, but each component should have only one reason to change. Image 1 - handles user profiles. But it has many reasons to change. Image 2 - implements each reason for changing in its own component:

Love the new Astro release. Honestly, I'm a big Astro fanboy and I built my blog neciudan.dev with it. I love the flexibility and ease to upgrade the project when a new release is live

❌ 'Too many useState hooks = use useReducer' ✅ 'Complex state logic = use useReducer' useState is fine for 5-6 independent states. useReducer shines when state updates affect each other. Ensure state colocation and when state manipulation gets complicated switch to useReducer. #React #WebDev

TIL the word "freelancer" comes from Medieval times - literally meaning a "free lance" warrior not bound to any lord! These mercenaries were the OG independent contractors, traveling castle to castle for work. Same spirit today, just with laptops instead of lances! 🗡️💻

Ever wondered how useMemo works under the hood? 🤔 It's not magic - React stores your result & deps in memoizedState, then during updates, compares deps before deciding to recalculate. But watch out! Sometimes the comparison itself is more expensive than just recalculating 🚀 #reactjs #webdev

Tomorrow is my first time hosting a meetup. I'm proud, nervous, and super excited. Wohooo! I'm so glad for the React Community in Barcelona, who showed such a huge interest in the event, but I'm also super thankful for everybody helping out.

Reading "Unreasonable Hospitality" by @WillGuidara changed how I code. Walt Disney said, "People can feel perfection," and it clicked - "good enough" isn't enough anymore. In the age of AI, unreasonable attention to UX will stand out. One delighted user is worth more than a %conversion

React has finally announced that they are deprecating CRA The recc to use something else has been in their official docs for a while, but I guess this makes it official They will still support React19 in maintenance mode, so if you are still a user, it is time to migrate to Tanstack Start, maybe.

🔥 State of React 2024 is out! useState still dominates (50%), TanStack Query rising (36%), and Jest remains testing king (70%) Most interesting? 78% are on React 18.x, while React 19 adoption is tiny. Full survey here: https://2024.stateofreact.com/en-US/
