  Hey Vaibhav

  Great job on this project. One common way of validating forms in react is to use a library called "react-hook-form" and "yup" if you use javascript, or "ZOD" if you use typescript.

  Here is an example of using Yup and react-hook-form:

  Step 1: Install Yup and React Hook Form

  npm install yup react-hook-form
  

  Step 2: Import the required dependencies

  import React from 'react';
  import { useForm } from 'react-hook-form';
  import { yupResolver } from '@hookform/resolvers/yup';
  import * as yup from 'yup';
  

  Step 3: Define your form schema using Yup For example, if you have a form with a name field and an email field, you can define the schema like this:

  const schema = yup.object().shape({
  name: yup.string().required('Name is required').min(2, 'Name should be at least 2 characters'),
  email: yup.string().required('Email is required').email('Invalid email address'),
  });
  

  Step 4: Use React Hook Form with Yup resolver Inside your React component, initialize the React Hook Form and specify the Yup resolver:

  const MyForm = () => {
  const { register, handleSubmit, formState: { errors } } = useForm({
  resolver: yupResolver(schema),
  });
  
  const onSubmit = (data) => {
  // Handle form submission
  console.log(data);
  };
  
  return (
  <form onSubmit={handleSubmit(onSubmit)}>
  <div>
  <label>Name</label>
  <input type="text" {...register('name')} />
  {errors.name && <p>{errors.name.message}</p>}
  </div>
  <div>
  <label>Email</label>
  <input type="text" {...register('email')} />
  {errors.email && <p>{errors.email.message}</p>}
  </div>
  <button type="submit">Submit</button>
  </form>
  );
  };
  

  In the code above, the register function from React Hook Form is used to register the form fields. The handleSubmit function is used to handle form submission. The errors object contains the validation errors from Yup, and it's used to display error messages for the corresponding fields.

  Step 5: Render the form Finally, render the <MyForm /> component wherever you want the form to appear in your application.
