• Detailed Phone Number Information: Get information like the type of phone number (mobile, fixed line, etc.) and region.

Installation 🔧

To install the library, run the following npm command:

npm install phonenum-info

## Usage 📚

1. Validate a Phone Number ✅
To validate a phone number for a specific country/region code, use the isValidPhonenumber function.

```javascript
const { isValidPhonenumber } = require('phonenum-info');

const phoneNumber = '7XXXXX0519'; // Example phone number
const regionCode = 'IQ'; // Region code (e.g., IQ for Iraq)

if (isValidPhonenumber(phoneNumber, regionCode)) {
  console.log("Phone number is valid.");
} else {
  console.log("Phone number is invalid.");
}


2. Get Phone Number Information ℹ️
To retrieve detailed information about the phone number, including its type, country code, and formatted outputs, use the phonenumbervalidator function.

```javascript
const { phonenumbervalidator } = require('phonenum-info');

const phoneNumber = '7XXXXX0519'; // Example phone number
const regionCode = 'IQ'; // Region code (e.g., IQ for Iraq)

const result = phonenumbervalidator(phoneNumber, regionCode);
console.log(result);

This will output something like:


7XXXXX0519 is a VALID MOBILE phone number for region - IQ

```javascript
const { possibilityOfPhoneNumber } = require('phonenum-info');

const phoneNumber = '7XXXXX0519'; // Example phone number
const result = possibilityOfPhoneNumber(phoneNumber, true); // `true` for detailed info

Alternatively, you can use false for more concise results:

const { possibilityOfPhoneNumber } = require('phonenum-info');

const phoneNumber = '7XXXXX0519'; // Example phone number
const result = possibilityOfPhoneNumber(phoneNumber, false); // `false` for concise info

console.log(result);

This will return a simplified array:

[
  {
    "Country": "Germany",
    "Number Type": "FIXED LINE",
    "International Format": "+49 7XXX XX0519"
  },
  {
    "Country": "India",
    "Number Type": "MOBILE",
    "International Format": "+91 7XXXX X0519"
  },
  {
    "Country": "Iran",
    "Number Type": "FIXED LINE",
    "International Format": "+98 7X XXXX 0519"
  },
  {
    "Country": "Iraq",
    "Number Type": "MOBILE",
    "International Format": "+964 7XX XXX 0519"
  },
  {
    "Country": "Luxembourg",
    "Number Type": "FIXED LINE",
    "International Format": "+352 7X XX XX 0519"
  },
  {
    "Country": "United Kingdom",
    "Number Type": "MOBILE",
    "International Format": "+44 7XXX XX0519"
  },
  {
    "Country": "United States",
    "Number Type": "FIXED LINE OR MOBILE",
    "International Format": "+1 7XX-XXX-0519"
  }
