bcrypt compare returns false code example

Example 1: bcrypt compare

import bcrypt from 'bcryptjs'

export const matchPassword = async (enteredpassword, oldPassword) => {
  return await bcrypt.compare(enteredpassword, oldPassword)
}

Example 2: 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);
    });
});

Example 3: bcrypt compare with hash

// password: the value passed from the password form input
// hash: the value requested from the database. This is the "encrypted" password
bcrypt.compare(password, hash).then(validPass => {
	// validPass returns true or false
    }.catch(err => console.log('error: ' + err));
