bcryptjs compare always false code example

Example: bcrypt compare return false

/*
  you can skip doing bcrypt.genSalt and use 
  bcrypt.hash(password, 10, function(err, hash) {..});
  this is working fine for me:
*/

var bcrypt = require('bcrypt');

bcrypt.hash('mypassword', 10, function(err, hash) {
    if (err) { throw (err); }

    bcrypt.compare('mypassword', hash, function(err, result) {
        if (err) { throw (err); }
        console.log(result);
    });
});
