Other information:

i rechecked the previous changes to typescript and i extended the solution to fix current errors that we have
i had an error when added a multiple validation for the same field

so to fix it this will check the 3 cases

1. Nested Children with validations
2. Multiple validations
3. Single validation line.

also i made the validation arguments optional you don't always need to validate every field.
