Your application has a dynamic form where fields can be added or removed based on user input. Which feature of Angular's Reactive Forms would you leverage to accomplish this?
- Create a separate component for each dynamic form field.
- Implement dynamic forms using Angular's template-driven approach.
- Use the ngIf directive to conditionally render form fields.
- Utilize form arrays to dynamically add or remove form controls.
In Angular's Reactive Forms, you would leverage form arrays to dynamically add or remove form controls based on user input in a dynamic form. The ngIf directive is more suitable for conditionally rendering existing elements in the DOM, not for dynamically managing form controls. Creating a separate component for each dynamic form field is not the recommended approach for dynamic forms, and Angular's template-driven approach is less flexible in handling dynamic forms than Reactive Forms with form arrays.
