validate phone number length between 5-15

I want to validated phone number in react native. Phone number minimum length should be 5 and maximum 15. I created a function for that but it's showing error when number is above 5. Can someone tell me how to validate it properly?

if (!/(^\d{15}$)|(^\d{5}-\d{4}$)/.test(phoneNumber)) {
      return strings.PLEASE_ENTER_PHONE_NUMBER_VALID;
    }

12345-1234 and 1234512345112345 both work as expected

Do you mean 5 to 15 digits are ok? Then you need

/(^\d{5,15}$)|(^\d{5}-\d{4}$)/

Like

const testPhone = phoneNumber => {
  if (!/(^\d{5,15}$)|(^\d{5}-\d{4}$)/.test(phoneNumber)) {
    return "PLEASE_ENTER_PHONE_NUMBER_VALID";
  }
  return "ok"
};

// ok:
console.log(testPhone("12345"))
console.log(testPhone("12345-1234"))
console.log(testPhone("1234512345"))
console.log(testPhone("123451234512345"))

//nok

console.log(testPhone("1234"))
console.log(testPhone("12345--1234"))
console.log(testPhone("12345123451234512345"))
