const myObj = { a: 1, b: 2 };
const { a, b } = myObj;
// is equivalent to:
// const a = myObj.a;
// const b = myObj.b;

 

 

const obj = { a: 1, b: 2 };
const { c, b } = obj;

 

const obj = { a: 1, b: { c: 2 } };
const { a, b: { c: d } } = obj;
// Two variables are bound: `a` and `d`

 

const obj = { a: "spam" }
const { a: x } = obj
