bcrypt generates different hash each time.

How come bcrypt generates different has each time I run it.

app.js 
var unsecurePlainTextPassword = "password";

var bcrypt = require('bcrypt');
var colors = require('colors');
bcrypt.genSalt(10, function(err, salt) {
    bcrypt.hash(unsecurePlainTextPassword, salt, function(err, hash){
        console.log(hash.green);
    });
});

> node app.js

Each time you run it the bcrypt.genSalt() function is generating a new salt. This salt is then used when hashing the password.
