nodejs - how to compare two hashes password of bcrypt

Question

Hello I need some help with this issue after I search the solution and I have not found yet,

I want to compare 2 hash password with bcrypt of the same password, how do I do it?

for example:

I have these 2 hash password that came from the same password in bcrypt:

var password = E@Js#07Do=U$
var hash1 = $2a$10$fKAyjaG0pCkisZfRpKsBxursD6QigXQpm1TaPBDZ4KhIZRguYPKHe
var hash2 = $2a$10$mgApOcRIp7RSK3lRIIlQ5e/GjVFbxAFytGAEc0Bo17..r8v2pPR22
// that's not working for me
bcrypt.compare(passwordHash, userPasswordLoginHash, function(err, isMatch) {
   if (err) throw err;
   if(isMatch){
      console.log('correct password!')
   }
   callback(null, isMatch);
});

how can i compare them, to determine that they came from the same password, by using bcryptjs npm package?

For a bit extra security you can encrypt the password in the front-end and decrypt and compare in the back-end
