// you can do something like this
let obj = { a: 1, b: 2, c: 3, d: 4 };
let clone = obj;
delete clone.b;
console.log(clone);
// { a: 1, c: 3, d: 4 }
// or you can do something like this
let obj = { a: 1, b: 2, c: 3, d: 4 }
let clone = (({ b, c, ...o }) => o)(obj) // remove b and c
console.log(clone)
// { a: 1, d: 4 }
