What does putting curly brackets around a variale when initializing it does exactly?

Question

Example :

const {http} = require('http');

I have seen something about "destructing" and have read some resources about that, but I am still very confused about what it actually does.

Answer 1

It extracts that property from the object.
The meaning of it is exacly the same as writing this:

const http = require('http').http;
