How to treat deep copy in vue

This article mainly introduces the relevant information about vue deep copy. It is very good and has reference value. Friends who need it can refer to it

The Object.assign() method is used to assign all enumerable attributes. Values ​​are copied from one or more source objects to the target object. It will return the target object.

const object1 = {
a: 1,
b: 2,
c: 3
};
const object2 = Object.assign({}, object1);
console.log(object2.c);
// expected output: 3

Or use

obj=JSON.parse(JSON.stringify(this.templateData)); //this.templateData是父组件传递的对象

Applicability

When an abstract model has two aspects, one of which depends on the other. Encapsulating the two in independent objects allows them to be changed and reused independently

When one object changes, other objects need to be changed at the same time, but we don’t know how many objects need to be changed.

When an object must notify other objects, but it does not know who the specific object is. In other words, you don't want these objects to be tightly coupled.

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
