compare always returns success

[EvaldasVasiliauskas]

no matter what password I pass, compare always returns success. Am I doing something wrong?
Here's an example of very primitive app:

var bcrypt = require('bcryptjs');

var mypass = 'B4c0/\/';
var mysalt = '';
var myhash = '';

mysalt = bcrypt.genSaltSync(10);
myhash = bcrypt.hashSync(mypass, mysalt);

bcrypt.compare(mypass + 'a', myhash)
.then(() => {console.log("Comparison was true")})
.catch(() => {console.log("Comparison was false")});

OS: Win x64
npm: 4.0.5
node: 7.4.0

I'd say the README example on promises (pr) is incorrect:

bcrypt.compare(mypass + 'a', myhash)
.then((res) => {console.log("Comparison was: " + res)})
.catch(() => {console.log("Exception thrown")});
