What does the spread operator do when used on an object, like {...obj}?
4 447
β
Answer: Theyβre 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.
Itβs 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 donβt notice.
On pebbl.fun, the version with the slash redirects to the one without it. So only one of them is the βrealβ page.
One practical difference that often trips people up is how relative links resolve (see the image). Thatβs why being consistent matters, especially with APIs.
Just use whichever version the docs show. Donβt assume the slash is optional.4 447

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: π― Methods (
GET, POST)
π― Headers
π― Cookies
π― 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.
π HTTPS isn't a different protocol. It's HTTP inside an encrypted tunnel.4 447

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 BEven 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.
