Angular Interview Practice

Two-way data binding is a key feature in Angular that allows for synchronization between a component's properties and the corresponding view (or template). This means that any changes made in the template are immediately reflected in the component and vice versa. This creates a seamless experience when handling user inputs, making it easier to manage state within applications.

When using two-way data binding, developers often utilize the "[(ngModel)]" directive, which binds the value of the input element to the component property and updates it as the user interacts with the form. This becomes particularly useful in scenarios where real-time updates of input fields are necessary, such as in forms or interactive components.

Other statements may misrepresent the concept. For instance, data flowing in one direction describes one-way data binding, while the idea that it is used exclusively for forms limits its applicability in broader contexts, such as dynamic UI updates. Lastly, two-way data binding is not deprecated in Angular; it remains a widely-used feature for enhancing the responsiveness of applications.
