Angular Interview Practice

The @ViewChild decorator in Angular is a powerful feature that allows developers to access child components, directives, or DOM elements from a parent component. When you use @ViewChild, you can reference a specific component or directive in the template and then interact with it programmatically in the parent component class.

For example, if there's a child component that exposes certain methods or properties, using @ViewChild enables the parent component to call those methods or directly modify its properties. This is particularly useful for implementing features that require direct manipulation of the child component, like calling a method to refresh data or enabling/disabling controls based on certain conditions.

In addition to accessing components, @ViewChild can also be used to get a reference to DOM elements, which allows you to perform tasks like manipulating styles or listening to events directly without needing to bind everything through Angular's templated approach.

By leveraging @ViewChild correctly, you enhance the interactivity and responsiveness of your application while maintaining clean and organized code structures within your components.
