client.login( authJSON )

This will use the credentials to connect & log back in. No need to call ``` connect() ``` after calling this function
10. If you want to query whether a number is registered on WhatsApp, use:
``` javascript
client.isOnWhatsApp ("[countrycode][some10digitnumber]@s.whatsapp.net", (exists, id) => {
if (exists) {
console.log(id + " is on WhatsApp")
} else {
console.log(id + " is not on WhatsApp :(")
}
})
```
Of course, replace ``` [countrycode][some10digitnumber] ``` with an actual country code & number
Do check out test.js to see example usage of all these functions.
