In JavaScript frameworks like React, data binding refers to the process of connecting the UI with the underlying data (state or props) so that when data changes, the UI updates automatically.

1. One-Way Data Binding (React’s model)

React uses one-way data binding, meaning data flows in a single direction:

State/Props → UI

• Components receive data via props or manage it via state.

• Changes in data cause React to re-render the affected parts of the UI.

Here:

• value={name} binds the input to the state.

• onChange updates the state.

• When name changes, the paragraph and input update.

2. Two-Way Binding (Manually implemented in React)

While React doesn’t have built-in two-way binding like Angular, you can achieve a similar effect by combining state updates and value binding, as shown above. This gives you full control over how and when updates occur.

3. Virtual DOM & Reconciliation

React uses the virtual DOM to detect changes from data binding and efficiently update only the changed parts of the real DOM.

Benefits of React’s One-Way Binding

• Predictable data flow

• Easier debugging and testing

• Clear component hierarchy

In summary, React’s data binding works by connecting state or props to the UI and updating the UI automatically when the data changes. This is primarily one-way, but two-way binding can be implemented with controlled components.
