javascript - 对象拆包赋值操作？

Question

JavaScript 中有这样的东西吗？基本上，我正在寻找这些方面的东西:

let obj_a = {test: "one", property: "two"};
let obj_b = {test: "1", other: "three"};
let obj_b ...= obj_a; // would be the equivalent of obj_b = {...obj_b, ...obj_a}

是否有类似的内置语法，或者这是我将在 ES6 中获得的最佳语法？

Object.assign会做。

let obj_a = { test: "one", property: "two" },
    obj_b = { test: "1", other: "three" };

Object.assign(obj_b, obj_a);

console.log(obj_b);
