Can you please explain what

const { hostname } = a;

does and how?

It has the same effect as:
const hostname = a.hostname

That's called destructuring assignment. "a" probably is an object which has the hostname property so that assignment extracts hostname.
I'm just writin about this 😅. Hopefully that'll help you.
