How is two-way binding in vue implemented?

How is two-way binding in vue implemented?

Vue's two-way data binding is implemented through the following steps: the data proxy is wrapped in a reactive proxy and listens for data changes. Data Hijack monitors object properties, detects value changes and triggers updates. Template compilation compiles the data binding syntax into an update function, triggering data changes to update the DOM. Event listening updates model data in response to user interaction and form input. Virtual DOM tracks DOM state, re-renders and applies changes to improve update efficiency. Bidirectional flow combines responsive proxies and virtual DOM to enable mutual updates of data and views.
