用Proxy可以实现类似功能么？

Question

想实现一个功能，我指定一个对象，比如

const obj = {
    name: "a",
    experience: [ { title: "JS", score: 34},{ title: "ES", score: 31} ],
    other: {
        property1: "1",
        property2: "2",
        property3: "3",
        property4: "4",
        
    }
}

当我给obj或者其子属性添加不存在的属性时，例如：obj.title ="wo"，obj.other.property7 = "7"，能够报错或者提示,又或者obj.other= { name: "1", propery1: "324"},"324"可以赋值成功，给experience可以push项。有没有比较好的思路？

obj = {
    name: "a",
    experience: [ { title: "JS", score: 34},{ title: "ES", score: 31} ],
    other: {
        property1: "1",
        property2: "2",
        property3: "3",
        property4: "4",
        
    }
}
proxy = new Proxy(obj,{
  set: function(target, property, value, receiver) {
    console.log(arguments, Object.hasOwnProperty(property), Object.isPrototypeOf(property))
    if(Object.hasOwnProperty(property)){
        target[property] = value;
    }else{
        throw new Error('报错了，不存在')
    }
    return true
  }
})
proxy.name = 'b'
console.log(obj)
proxy.name1 = 'b'
console.log(obj)
