Clear all inputs and errors. Call the resend API. Start a timer (e.g., 30 seconds) during which the resend button is disabled. When the timer ends, enable the resend button again.

Filter non-numeric characters on input (replace(/\D/g, '')). Check completion (all inputs filled). Send the OTP to the server for verification. Show errors for invalid OTP. Clear inputs on error and focus the first one for retry.
Show an error message below the inputs. Add a red border to the inputs (CSS class 'error'). Clear the inputs and focus the first one for retry. Clear errors when the user starts typing again.
Join all input values: Array.from(inputs).map(input => input.value).join(''). This gives a string like '1234' from 4 separate inputs.
