QUESTION 2

1. Which of the following is an advantage of using controlled inputs? Check all that apply.

   		front-end authentication of users
   		in-place feedback, like validations
   		disabling a button unless all fields have valid data
   		enforcing a specific input format, like credit card numbers

Answer 1

Answer Option B

Reason: Option B is correct and rest of the option are because in a react lifecycle. At first, ComponentWillMount will run before informing the server on the client as well as the host.

Then ComponentDidMount comes after render is done only on the client

The ComponentDidUpdate is called after the rendering is done

The ComponentWillUnMount comes after the component is unmounted from the dom

Answer 2) Option B,C and D

Reason: Option A is incorrect because controlled inputs are not used to authenticate user.

Option B is correct because in place feedback like validation can be used by controlled inputs in order to add a dynamic feature.

Option C is correct because we can disable a data or update something dynamically in order to provide an additional data.

Option D is correct because it can be used to force the user to provide the input in a specific order.
