Data Binding

Data binding is a programming technique used to establish a dynamic connection between a user interface (UI) and the underlying data model. It ensures that changes in the data automatically reflect in the UI and vice versa, reducing the need for manual updates.

This concept is widely used in frameworks like Angular, React, and Vue.js. Data binding can be one-way, where data flows from the model to the UI, or two-way, where changes in the UI also update the model. For example, in a shopping cart, modifying the quantity of an item updates the total price in real-time using two-way binding.

By automating synchronization, data binding simplifies coding, enhances efficiency, and creates interactive, responsive applications. It’s an essential tool for modern web and mobile development.
