Vue.js theory!

1, aside from the manual operation of the DOM thinking, Vue.js is data-driven, you do not have to manually manipulate the DOM.


2, the DOM and data are bound together, the DOM will be synchronized with the data, whenever the data changes, the DOM will be updated accordingly.


3. MVVM Mode (Model-view-viewmodel)

How ViewModel interacts with the view and model.

Model is placed in data (possibly multiple)

View placed in El (View {{}} may have many items corresponding to model)


4, ViewModel is the core of vue.js, it is a Vue instance.

The Vue instance acts on an HTML element,

This element can be the BODY element of the HTML,

It can also be an element that has an ID specified.


5. All elements are responsive
