How can I implement email validation in React.js?
This is an example of an email validation form using React.js. The code sets up a functional component called App using React hooks. It utilizes the useState hook to manage the email state, validation state, and submission state.
The component renders a form with an input field for the email and a submit button. When the input value changes, the handleInputChange function is called to update the email state and reset the submission state.
Upon form submission, the handleSubmit function is triggered. It uses a regular expression to validate the email format and sets the validation state accordingly. The submission state is set to true.
Based on the validation and submission states, conditional rendering is performed. If the form is submitted and the email is valid, a success message is displayed in green. If the form is submitted and the email is invalid, an error message is displayed in red.
