## Migration Guide (v1.x to v2.0)

### Breaking Changes

1. **TypeScript Types**: If you were using types:

   ```typescript
   // Old (v1.x)
   import { CountryProperty } from "country-codes-list";
   const prop: CountryProperty = CountryProperty.countryCode;

   // New (v2.0)
   import type { CountryProperty } from "country-codes-list";
   const prop: CountryProperty = "countryCode";
   ```

2. **Module Imports**: Now supports both CommonJS and ES modules:

   ```javascript
   // CommonJS (still works)
   const countryCodes = require("country-codes-list");

   // ES Modules (new)
   import * as countryCodes from "country-codes-list";
   ```

3. **Stricter Types**: Some functions now have stricter type checking:
   ```typescript
   // This now requires valid country property keys
   countryCodes.filter("invalidKey", "value"); // TypeScript error
   ```

## Usage

This package can be used in both CommonJS (JavaScript) and TypeScript environments.

### CommonJS

```js
const countryCodes = require("country-codes-list");

const myCountryCodesObject = countryCodes.customList(
  "countryCode",
  "[{countryCode}] {countryNameEn}: +{countryCallingCode}"
);

console.log(myCountryCodesObject);
```

### TypeScript

```ts
import * as countryCodes from "country-codes-list";

const myCountryCodesObject = countryCodes.customList(
  "countryCode",
  "[{countryCode}] {countryNameEn}: +{countryCallingCode}"
);
console.log(myCountryCodesObject);
```

### API Details – customList Method

- The first parameter is the key used for the returned object's property.
- The second parameter is a string with placeholders (in `{placeholder}` format) replaced by corresponding country properties.

The available placeholders are:

- `countryNameEn`
- `countryNameLocal`
- `countryCode`
- `currencyCode`
- `currencyNameEn`
- `tinType`
- `tinName`
- `officialLanguageCode`
- `officialLanguageNameEn`
- `officialLanguageNameLocal`
- `countryCallingCode`
- `region`
- `globalSouth`

#### Example

```js
const countryCodes = require("country-codes-list");

const myCountryCodesObject = countryCodes.customList(
  "countryCode",
  "[{countryCode}] {countryNameEn}: +{countryCallingCode}"
);
```

This will return an object like this one:

```js
{
    'AD': '[AD] Andorra: +376',
    'AE': '[AE] United Arab Emirates: +971',
    'AF': '[AF] Afghanistan: +93',
    'AG': '[AG] Antigua and Barbuda: +1',
    'AI': '[AI] Anguilla: +1',
    'AL': '[AL] Albania: +355',
    'AM': '[AM] Armenia: +374',
    'AO': '[AO] Angola: +244',
    'AQ': '[AQ] Antarctica: +',
    'AR': '[AR] Argentina: +54',
    'AS': '[AS] American Samoa: +1',
    'AT': '[AT] Austria: +43',
    'AU': '[AU] Australia: +61',
    'AW': '[AW] Aruba: +297',
    ...
}

```
