I am trying to set the variable passHash (that is outside of bcrypt's hash function) to bcrypt-generated hash parameter but passHash is still returning an empty string. But, when I print hash on its own, it correctly prints a hash. Does anyone know of a solution to this? Thanks!

Code:

    let passHash = '';

    bcrypt.hash(code, 10, function (err, hash) {
         passHash = hash;
    });

    //Output: passHash = '';
