What common performance issues do beginners face when developing web apps with Vibe?

Honestly, a lot of performance problems stem from smaller issues rather than a single culprit. For example, if you're using React or Next.js, look out for useless re-renders. These little things can add up to a noticeable slowdown.

One of the best things you can do is really examine your app for small issues that can add up. Beginners often overlook things like oversized images, unnecessary re-renders, and not implementing code splitting effectively. Tackling these can significantly improve load times.

I see a lot of beginners making similar mistakes, like unnecessary API calls with every route change or using heavy libraries when lighter ones could do the job. Also, remember to optimize your images ahead of time; if not, your app might default to pulling huge images from sources like Unsplash!
