About

1. I created the BankAccountService class to provide the functionalities outlined in the spec:
   • Account creation -> createBankAccount()
   • Deposit -> deposit()
   • Withdrawal -> withdraw()
   • Transfer -> transfer
   • Account balance: -> getBalanceOfAccount()
2. Data is stored in memory in the BankAccountRepository class via class variables.
   • This is a singleton class initialized in init.ts.
3. I've also created the user-accounts domain to mimic real life business flow where:
   • Ony valid users within your application should be able to create bank accounts
   • Users can create multiple bank accounts
