if (name.trim() === "") { /* show name error */ }
if (!/^[^\\s@]+@[^\\s@]+\\.[^\\s@]+$/.test(email)) { /* email error */ }
if (password.length < 6) { /* password too short */ }
if (password !== confirmation) { /* mismatch */ }
if (!Number.isFinite(age) || age < 18 || age > 60) { /* age error */ }Correction / सुधार: The uploaded source has misspellings and syntax errors such as return fales, return ture, missing quotes, and references to the wrong field name. The corrected program consistently uses field IDs and returns clear messages. Front-end validation is not a substitute for server-side validation.
