How do you prevent users from skipping unvalidated steps in a multi-step form?
Before jumping to step N, validate all steps from 0 to N-1. If any is invalid, jump to the first invalid step and show the error. This ensures the user cannot skip to a later step without filling in required data.

Use a single object for all form data: const formData = { name: '', email: '', address: '' }. Update on every input change. The object persists across steps because it is in the outer scope, not re-created on each render.
Check required fields and format. For each field in the current step: if required and empty, show error. If email, check regex. If invalid, prevent navigation. Return true only if all fields pass.
Calculate: ((currentStep + 1) / steps.length) * 100. Set the progress bar width to this percentage. Update on every step change. This gives the user a visual indication of how far they are in the form.
