Object.assign正是您所需要的：
// declare obj with some props
const btn = {
? innerText: "initial"
};
// see what we have
console.log(JSON.stringify(btn))
// assign (and re-assign) some props
Object.assign(btn, {
? innerText: "hello",
? style: {
? ? fontSize: "24px",
? ? outline: "none"
? }
})
// see what changed
console.log(JSON.stringify(btn))

您可以使用文字對象初始值設(shè)定項：
let a = 1, b=2, c=3
const newObj = {a,b,c};
console.log(newObj.a);
// expected output: 1
