what is object.assign? code example

Example 1: object assign

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 }

Example 2: Object.assign()

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}
