        </div>
    </form>

im must do function? i have problem with regex, in input im see '_' character and user.number.length counts it as a sign

Answer 1

It might be confusing

number

property of your model with typescript number type. Did you try changing number with mobile_number or some other name?

TypeScript Basic Types

I normally use 'digit' that comes with this package. It is also good when you want to build with --aot
