How to add in 4 alphanumeric with space in Text Input?

I would like to add a TextInput in this format:-

I getting this code but it just apply for numeric only.

_handlingCardNumber(number) {
  this.setState({
    cardNumber: number.replace(/s?/g, '').replace(/(d{4})/g, '$1 ').trim()
  });
}

How can I do it for numeric & string?
