bookChallenge: Build a Controlled Form Component

Task

In this challenge, you will create a Form component with two input fields: email and password. The goal is to use the useRef hook to reference the input elements and handle form submission logic.

Instructions

  1. Import the useRef hook from the react library.
  2. Inside the Form component, declare two useRef variables: emailRef and passwordRef, initialized with null.
  3. Reset the input fields by setting their values to an empty string using the useRef variables.
  1. To import the necessary hook from the React library, include anΒ importΒ statement.
  2. For this task, we will utilize theΒ useRefΒ hook to store data without affecting the markup.
  3. To determine the appropriate variable name for the ref, choose a word that is associated with the ref and add "Ref" at the end.
  4. To initialize the ref withΒ null, passΒ nullΒ as the initial value in the brackets of theΒ useRefΒ hook (e.g.,Β useRef(null)).
  5. To reset the form input, use the appropriate ref variable and assign itsΒ .current.valueΒ to an empty string ("").
