1. define function

            const handleCreate = async () => {
                const res = await fetch('https://jsonplaceholder.typicode.com/users', {
                  method: 'POST',
                  headers: {

                  body: JSON.stringify({
                    name: 'New User',
                    email: 'new@example.com'
                  })
