How to execute when props and methods method name conflict?

The props property in Vue is used to pass values between components. Its main function and meaning is to receive data from the outside. It is equivalent to data and methods.When the attributes in the newly added mixins.js file conflict with the attributes in the component, such as the data attribute, methods attribute, etc., the attributes in the component shall prevail. If there is no conflict, the incoming props will be executed. But there are special ones: when there is a conflict between the lifecycle hook functions, the hooks passed in by props or in mixins.js are used first.

The following is an actual small demonstration case

//mixins.js
export const mix={ 
methods: {
        show(){
            alert("11111");
        }
    }
}

//App.vue
export default {
    name: "Student",
    methods:{
        show(){
          alert("666600000!!!");
        }    
     }

Resulat://666600000!!!

Js uses recursive way to traverse the dom tree to dynamically create element nodes

What is a dom tree? In short, DOM is the Document Object Model, which provides a structured representation for documents and defines how to access the document structure through scripts. DOM is composed of nodes. After the HTML is loaded, the rendering engine will generate a DOM tree in memory based on the HTML document. This article uses a small case to traverse the dom tree recursively. The core of the method is to determine whether the incoming data is an array, and then traverse the root node. Note that there must be an end condition when using recursion.
