ChanceJS UK Phone Numbers

ChanceJSUKPhoneNumbers.js

/*
ChanceJS (http://chancejs.com) doesn't do UK phone numbers, but you can get close by using chance.string with a 
pool of numbers 0-9 and length 9, then running it through replace with a bit of regex and 
adding a 01 for landline or a 07 for mobiles that will come out correctly formatted with spaces.
Not perfect, and most numbers not real, but it looks better than the US numbers when testing.

var contactNumbers = {
  telephone:  chance.string({pool: '0123456789', length: 9}).replace(/(\d{2})(\d{3})/g, "01$1 $2 "),
  mobile:     chance.string({pool: '0123456789', length: 9}).replace(/(\d{2})(\d{3})/g, "07$1 $2 ")
};
