Cheerful Cod
const obj = { a: 1 };
const copy = Object.assign({}, obj);
console.log(copy); // { a: 1 }
const target = { a: 1, b: 2 };
const source = { b: 4, c: 5 };
const returnedTarget = Object.assign(target, source);

// expected output: Object { a: 1, b: 4, c: 5 }

// expected output: Object { a: 1, b: 4, c: 5 }
The Object.assign() method copies all enumerable own properties from one or more source objects to a target object. It returns the target object.
const target = { a: 1, b: 2 };
const source = { b: 4, c: 5 };
const returnedTarget = Object.assign(target, source);
console.log(target);
// expected output: Object { a: 1, b: 4, c: 5 }
console.log(returnedTarget);
// expected output: Object { a: 1, b: 4, c: 5 }// Object assign in javascript
let fname = { firstName : 'Black' };
let lname = { lastName : 'Panther'}
let full_names = Object.assign(fname, lname);
console.log(full_names); //{ firstName: 'Black', lastName: 'Panther' }const obj1 = {
a: 5,
b: 2
}
const obj2 = Object.assign({a:6 d:7}, obj1);
console.log(obj2);
// output: { a: 5 , b: 2, d:7} const newId= tours[tours.length-1].id+1;
const newTour= Object.assign({id:newId},req.body) //object.assign() is used to merge two objects.
