| 5 |  📕Quick React Tip:
Don't subscribe to data that you don't render; it causes unnecessary rerenders. If it's only used in event handlers, read it there.
AI coding agents tend to get this wrong. | 238 |

| 7 | What does the spread operator do when used on an object, like {...obj}? | 261 |
| 8 |  API Gatway: Cheatsheet | 287 |
| 9 |  ✅ 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. | 262 |

| 19 |  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. | 380 |
