Two-way data binding refers to the two-way association of data in the view and data in the model. The principle of two-way data binding is mainly based on creating models, establishing views, binding data, updating views, listening to events, processing business logic and updating views, etc. Two-way data binding is a mechanism that associates views with models, allowing data in an application to be easily passed and updated between views and models. By using two-way data binding, you can reduce the amount of code written to manually maintain data associations and improve the maintainability and readability of your application.

Two-way data binding refers to the two-way association of data in the view (user interface) and data in the model (business logic). When the data in the view changes, the data in the model will be updated; similarly, when the data in the model changes, the data in the view will also be updated. This association is automatic, and there is no need to manually write a lot of code to maintain this association.
The principle of two-way data binding is mainly based on the following steps:
The implementation of two-way data binding may vary between different frameworks and technologies. For example, in React, we use state and props to implement two-way data binding; in Vue, we use data binding syntax and computed properties to implement two-way data binding; in Angular, we Use two-way data binding syntax and controllers to implement two-way data binding.
In short, two-way data binding is a mechanism that associates views with models, which allows data in the application to be easily transferred and updated between views and models. By using two-way data binding, we can reduce the amount of code written to manually maintain data associations and improve the maintainability and readability of our applications.
