Object.assign的使用

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 }

console.log(returnedTarget === target);

let page = {
	current: 1,
    size: 2
}
let params = {
	params: 22,
}

let searchForm = {
	id: 11,
  	departId: 33
}

let test = Object.assign(
  page,
  params,
  searchForm
);

console.log(test);
