Web Development

Your vibe coded website looks finished, But It's not. Here are 20 things developers often forget before launch: • Custom 404 page • Unique meta title on every page • Meta description on every page • Clear CTA above the fold • Complete favicon set • robots.txt file • sitemap.xml • Open Graph image and metadata • Descriptive alt text for every image • Responsive mobile breakpoints • Sticky mobile CTA where appropriate • Loading and skeleton states • Form validation and error states • Thank-you or success page • Privacy policy page • Terms and conditions • Cookie consent banner, where required • Analytics and conversion tracking • Real business contact details • Compressed, optimized images Pretty is easy. Shipping properly is the real skill. 🔖

✅ Answer: They’re not the same. /api/users and /api/users/ are two different URLs. The trailing slash is part of the path, so the browser and server see them as separate addresses. It’s not a browser thing. Browsers just send whatever you type. The server (or the framework the programmer set up) decides what to do with each one. Some servers treat them as completely different pages, others automatically redirect one to the other so users don’t notice. On pebbl.fun, the version with the slash redirects to the one without it. So only one of them is the “real” page. One practical difference that often trips people up is how relative links resolve (see the image). That’s why being consistent matters, especially with APIs. Just use whichever version the docs show. Don’t assume the slash is optional.

Are they actually the same?

What Actually Is HTTPS?

HTTPS is HTTP running over TLS (Transport Layer Security).

TLS is responsible for encrypting the communication. HTTP still handles things like: 🎯 Methods (GET, POST) 🎯 Headers 🎯 Cookies 🎯 Status codes Before any HTTP data is exchanged, the browser and server perform a TLS handshake. During this process they: - Verify the server's identity using its certificate. - Agree on an encryption algorithm. - Generate shared encryption keys. Only after that does the browser send the first HTTP request. Without TLS, every request and response could be read or modified while travelling across the network. 👉 HTTPS isn't a different protocol. It's HTTP inside an encrypted tunnel.

The Microtask Queue Promises don't execute immediately after they resolve. They wait their turn. The Microtask Queue is a queue that stores callbacks from resolved Promises before they're executed. Consider:

console.log("A");

Promise.resolve().then(() => console.log("B"));

console.log("C");

The output is:

A
C
B

Even though the Promise resolves immediately, its callback is placed into the Microtask Queue. JavaScript finishes the current execution first. Only then does it process queued microtasks. This is the reason why Promise callbacks always run after synchronous code, even when no network request is involved.
