What is the difference between one-way and two-way data binding?

What is the difference between one-way and two-way data binding?

One-way data binding means data flows in one direction, from the model to the view. Two-way data binding allows data to flow both ways, meaning changes in the view update the model and vice versa.

Can you give me an example of each?

Sure! In one-way binding, if you have a text input that displays a user's name, changing the name in the model updates the input. In two-way binding, if the user changes the name in the input, it also updates the model automatically.

What are the advantages of two-way binding?

Two-way binding simplifies synchronization between the model and view, making it easier to manage user input and dynamic updates without additional code.

Are there any downsides to using two-way binding?

Yes, two-way binding can lead to more complex debugging and performance issues, especially in large applications, as changes can propagate in unexpected ways.
