/**
|
||
|
|
* Checks if a given phone number is valid.
|
||
|
|
*
|
||
|
|
* If the `number` is a string, it will be parsed to an object,
|
||
|
|
* but only if it contains only valid phone number characters (including punctuation).
|
||
|
|
* If the `number` is an object, it is used as is.
|
||
|
|
*
|
||
|
|
* The optional `defaultCountry` argument is the default country.
|
||
|
|
* I.e. it does not restrict to just that country,
|
||
|
|
* e.g. in those cases where several countries share
|
||
|
|
* the same phone numbering rules (NANPA, Britain, etc).
|
||
|
|
* For example, even though the number `07624 369230`
|
||
|
|
* belongs to the Isle of Man ("IM" country code)
|
||
|
|
* calling `isValidNumber('07624369230', 'GB', metadata)`
|
||
|
|
* still returns `true` because the country is not restricted to `GB`,
|
||
|
|
* it's just that `GB` is the default one for the phone numbering rules.
|
||
|
|
* For restricting the country see `isValidNumberForRegion()`
|
||
|
|
* though restricting a country might not be a good idea.

* Examples:

|
|
*
|
||
|
|
* ```js
|
||
|
|
* isValidNumber('+78005553535', metadata)
|
||
|
|
* isValidNumber('8005553535', 'RU', metadata)
|
||
|
|
* isValidNumber('88005553535', 'RU', metadata)
|
||
|
|
* isValidNumber({ phone: '8005553535', country: 'RU' }, metadata)
