# Self-review: Create a registration form - Advanced React

1. **When you need to change the password state, which is stored as an object with two properties,** `value` **and** `isTouched`**, how should you correctly use the** `setPassword` **state setter inside the** `onChange` **event handler?**
    
    * <mark>setPassword({ ...password, value: </mark> [<mark>e.target</mark>](http://e.target)<mark>.value });</mark>
        
    * setPassword({ isTouched: false, value: [e.target](http://e.target).value });
        
    * setPassword({ value: [e.target](http://e.target).value });
        
2. **What’s the correct event prop you should use to determine when an input has been interacted with at least once?**
    
    * onFocus
        
    * <mark>onBlur</mark>
        
    * onChange
        
3. **How do you prevent the default behavior of the form HTML tag in React when a submission event occurs?**
    
    * By returning false from the onSubmit function prop that the form tag provides.
        
    * By calling preventDefault on the event object inside any onChange handler from an input tag.
        
    * <mark>By calling preventDefault on the event object inside the onSubmit function prop from the form tag.</mark>
