What are the differences between one-way and two-way data binding in React?

What are the differences between one-way and two-way data binding in React?

In React, one-way data binding means that data flows in a single direction, from parent to child components. In contrast, two-way data binding allows for data to flow both ways, enabling child components to update the parent state.

Can you give me an example of one-way data binding?

Sure! In one-way data binding, you might have a parent component that passes a prop to a child component. The child can display the prop but cannot modify it directly.

What about two-way data binding? How does that work?

Two-way data binding is often implemented using controlled components in React. For example, an input field can update the state in the parent component whenever the user types, and the parent can also update the input's value.

Which one is better to use in React?

It depends on the use case. One-way data binding is generally preferred in React for its simplicity and predictability, while two-way data binding can be useful in forms where user input needs to be reflected immediately.
