const a = {
b: {
c: 'Hi!'

Is it possible rename b in this case? I want get c and also rename b.

You could destructure with a renaming and take the same property for destructuring.

const a = { b: { c: 'Hi!' } };
const { b: formerB, b: { c } } = a;


console.log(formerB)
console.log(c);

You can destructure the same property multiple times, onto different targets:

const { b: {c}, b: d } = a;

This assigns a.b.c to c and a.b to d.
