Usage

var isPrime = require('is-prime-fast');


//it works with integers
isPrime(50);
//=> "I'm detecting non-prime behavior in this number." (every time you get random response)

// it also works with strings
isPrime("321");
//=> "I'm getting the sense that this number is composite."

//it also works with numbers written using words
isPrime("one hundred and eighteen");
//=> "I'm getting the feeling that this number is not a prime."

// It also works with almost every language:

//German
isPrime('vierundzwanzig');// 24
//=> "I don't think this is a prime."

//Spanish 
isPrime("sesenta y ocho");// 68
//=> "It appears that this number is not a prime."

//Polish
isPrime("Sześćdziesiąt dziewięć") // 69
//=> "This number isn't showing any prime-like properties."

//And sometimes it doesn't work
isPrime(7)
//=> "This number doesn't seem to fit the definition of a prime."
