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 data 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 data binding, if the user changes the name in the input, it automatically updates the model as well.

What are the advantages of using two-way data binding?

Two-way data binding simplifies synchronization between the model and the view, making it easier to manage state in applications, especially in frameworks like Angular.

Are there any downsides to two-way data binding?

Yes, it can lead to more complex code and potential performance issues, as changes in the view can trigger multiple updates in the model.
