如何将金额从一个用户余额转移到另一用户余额？

Question

<script>
    function Account(UserId, Balance) {
        this.UserId = UserId;
        this.Balance = Balance;
    }

    Account.prototype.deposit = function (amount) {
        if (this._isPositive(amount)) {
            this.balance += amount;
            console.info(`Deposit: ${this.name} new balance is ${this.balance}`);
            return true;
        }
        return false;
    }

    Account.prototype.withdraw = function (amount) {
        if (this._isAllowed(amount)) {
            this.balance -= amount;
            console.info(`Withdraw: ${this.name} new balance is ${this.balance}`);
            return true;
        }
        return false;
    }

    Account.prototype.transfer = function (amount, account) {
        if (this.withdraw(amount) && account.deposit(amount)) {
            console.info(`Transfer: ${amount} has been moved from ${this.name} to ${account.name}`);
            return true;
        }
        return false;
    }

    Account.prototype._isPositive = function (amount) {
        const isPositive = amount > 0;
        if (!isPositive) {
            console.error('Amount must be positive!');
            return false;
        }
        return true;
    }

    Account.prototype._isAllowed = function (amount) {
        if (!this._isPositive(amount)) return false;

        const isAllowed = this.balance - amount >= 0;
        if (!isAllowed) {
            console.error('You have insufficent funds!');
            return false;
        }
        return true;
    }

    function transferring() {
        mary21.transfer(100.00, john456);
    }
</script>

我正在尝试将金额从一个用户余额转移到另一个用户余额。我可以知道如何在我的项目中使用此javascript。我正在使用.Net MVC，所以不确定在View或Controller中完成事务。
