Where to start with a simple banking app? [closed]

By -

I'm working through a course on JavaScript currently and honestly I'm having a pretty difficult time with it. If anyone has any resources they could recommend for learning, I'd appreciate it!

I'm trying to make a simple banking app with these requirements:

  • The user should see a prompt so they can type which action to perform.

  • The user will have a list of 4 actions to choose from.

  • Enter Q to quit (immediately quits the program).

  • Enter W to withdraw.

    • The user will be prompted again to enter an amount to withdraw. After withdrawing money, they should be able to type another option.

  • Enter D to deposit.

    • The user will be prompted again to enter an amount to deposit. After depositing money, they should be able to type another option.

  • Enter B to view balance.

    • The user will see their balance. Afterwards, they should be able to type another option.

  • The balance should update after any Withdrawal or Deposit transactions.

  • The program will loop asking for input until the user enters Q.

Here's my basic HTML for a very simple site

<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8">
    <title></title>
  </head>
  <body>
    <h1>Welcome!</h1>
    <button onclick="start()">Click here to get started.</button>
    <script src="scripts.js"></script>
  </body>
</html>

And here's as far as I've been able to get with the JS...

function start() {
  let input = prompt('What would you like to do?');

  if input = 'w' {
    alert('Withdraw');
  } else () {

  }
}

And I know that's probably not even the direction I need to be going. I'm honestly stuck because I don't really know where to start. Any and all advice is much appreciated, TIA!!

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure.

Spring Boot and Vaadin : Filtering rows in Vaadin Grid

By -
Adding a text field for filtering: Start by adding a text field above the grid. Remember, MainView is a VerticalLayout, so you need to add the text field before the grid. MainView.java public class MainView extends VerticalLayout {   private ContactService contactService;   private Grid<Contact> grid = new Grid<>(Contact.class);   private TextField filterText = new TextField(); ①   public MainView(ContactService contactService) {   this.contactService = contactService;   addClassName("list-view");   setSizeFull();   configureFilter(); ②   configureGrid();   add(filterText, grid); ③   updateList();   }   private void configureFilter() {   filterText.setPlaceholder("Filter by name..."); ④   filterText.setClearButtonVisible(true); ⑤   filterText.setValueChangeMode(ValueChangeMode.LAZY); ⑥   filterText.addValueChangeListener(e -> updateList()); ⑦   }   // Grid...
