2. User submits form
3. User input is validated in their browser
4. Data from the form is sent to a form processing script (Node.js or PHP, usually)
   1. Not all forms are sent to a server. Some forms such as calculators can be processed locally.
5. Form data is processed (either client-side or server-side)
