What are the best practices for two-way data binding?

Two-way data binding allows for automatic synchronization between the model and the view. Best practices include using frameworks that support it, like Angular or Vue.js, and ensuring that data flows are clear to avoid confusion.

Can you explain how it works in Angular?

In Angular, two-way data binding is achieved using the [(ngModel)] directive. This binds the input field to a property in the component, allowing changes in the input to update the model and vice versa.

What are some common pitfalls to avoid?

Common pitfalls include overusing two-way binding, which can lead to performance issues, and not properly managing the state, which can cause unexpected behavior in the application.

How does it differ from one-way data binding?

One-way data binding only allows data to flow in one direction, from the model to the view or vice versa, while two-way data binding allows for bidirectional data flow, making it more dynamic.

Can you give an example of a use case?

A common use case for two-way data binding is in forms, where user input needs to be reflected in the application state immediately, such as in a live search feature.
