var fnv = require('fnv-plus'),

    ahash52 = fnv.hash(astring),        // 52-bit hash by default
    ahash64 = fnv.hash(astring, 64);    // 64-bit hash specified

console.log(ahash52.hex() == 'a65e7023cd59e');    //true
console.log(ahash52.str() == 'stglysbf6m');       //true
console.log(ahash52.dec() == '2926792616498590'); //true

console.log(ahash64.hex() == '779a65e7023cd2e7');     //true
console.log(ahash64.str() == '1th7cxzlyc0dj');        //true
console.log(ahash64.dec() == '8618312879776256743');  //true

// fast variants
console.log(fnv.fast1a32hex(astring) == 'd58b3fa7');      //true
console.log(fnv.fast1a52hex(astring) == 'a65e7023cd59e'); //true

fnv.seed('foobar testseed');
console.log(fnv.hash(astring, 64).hex() == ahash64.hex()); // false
// ^^ because the default seed is not 'foobar testseed'
