You have a requirement to build a complex multi-step form with the ability to navigate between steps and validate each step individually. What approach would you take in Angular to handle this?

To build a complex multi-step form with navigation and individual step validation, it's advisable to create separate components for each form step in Angular. This approach promotes code modularity, makes step validation and navigation easier, and improves maintainability. Using a single large form with form groups can become unwieldy, and implementing custom form controls for each step might be overcomplicated. The ngSwitch directive is more for conditionally rendering content than for step navigation.
