Javascript 中使用 const 与 freeze 的声明

const product = {name: "sugar", weight: "1 kg"};product.name = "some new name";console.log(product);

{  name: "some new name",  weight: "1 kg"}

const product = {name: "sugar", weight: "1 kg"};object.freeze(product);product.name = "some new name";console.log(product);

{  name: "Sugar",  weight: "1 kg"}
